Feature: Order Service Provider, Order Events Observers

This commit introduces a RecommendationService that is used when indexing products.

The service is utilizing a recommendation rules interface, so many rules can be created and applied during indexing the products

+## [0.11.1] - 2026-09-01
+
+### Fixed
+- `Modules\Core\Catalog\Services\RecommendationService::recommend()` built its result with the base `Illuminate\Support\Collection` (`collect()`) instead of `Illuminate\Database\Eloquent\Collection`, even though every element is a `Product` model. `ProductIndexer::toSearchableArray()` calling `->load(['media', 'variants.prices'])` on that result threw `BadMethodCallException: Method Illuminate\Support\Collection::load does not exist` — silently failing every `MakeSearchable` queue job for a saved product (visible only as `FAIL` in the queue log, with the real exception in `storage/logs/laravel.log`). Fixed by having `RecommendationService` accumulate into a real `Eloquent\Collection` from the start.
+
+## [0.11.0] - 2026-09-01
+
+### Added
+- `Modules\Core\Catalog\Services\RecommendationService` — computes "related products" for a given product as a configurable, ordered chain of strategies (`config('catalog.recommendation_rules')`), not one hardcoded rule. Tops up from each successive rule until the limit (default 4) is reached or every rule is exhausted — e.g. 3 products from a same-category rule plus 1 from a random fallback — deduplicated across rules so the same product is never returned twice. Ships with `Modules\Core\Catalog\Recommendations\SameCategoryRule` (other products sharing the source product's first collection) and `RandomRule` (the universal fallback, placed last in the default chain). A new rule is just a class implementing `Modules\Core\Catalog\Contracts\RecommendationRule`. Documented in `docs/product-recommendations.md`.
+- `Modules\Core\Catalog\Services\ProductIndexer` embeds the result directly into each product's own Meilisearch document as `recommendations: [{id, name, price, image}, ...]` (`recommendations.id` filterable) — a product detail page renders its "related products" section with zero extra queries, same reasoning as the existing `collections` field. Deliberately embeds an `id` for the view to build a locale-correct URL from, not a resolved `href` — `product.show` is locale-prefixed, so a URL baked in at index time would only be correct for whichever locale happened to be active during that index run.
+- `Modules\Core\Catalog\Events\ProductSaved`/`ProductDeleted`, dispatched from `Product::saved()`/`Product::deleted()` in `CatalogServiceProvider` (the latter fires for both a soft delete and a force delete, matching Scout's own `unsearchable()` trigger point) — feed `Modules\Core\Catalog\Listeners\ReindexProductsRecommendingProduct`, which reverse-searches Meilisearch for every product currently recommending the changed/deleted one (`recommendations.id = "..."` — there's no Postgres relation for this, a recommendation only exists inside the index) and re-indexes them via Scout's own `->searchable()`. Product creation is deliberately not hooked into this: a new product not yet appearing as a recommendation elsewhere is an accepted staleness window, the same tradeoff already documented for `in_stock`/`price` — see `docs/product-recommendations.md`.
+- `CatalogServiceProvider` schedules `lunar:search:index "Lunar\Models\Product" --refresh` daily at 03:00 — a safety net on top of the event-driven reindexing above, covering a newly-created product not yet appearing as a recommendation and any other drift already accepted between reindexes. `--refresh` also re-syncs filterable/sortable index settings, not just documents.
+
+## [0.10.1] - 2026-09-01
+
+### Added
+- `Modules\Core\Localization\Services\StorefrontLabels::all()` gains three keys found missing from `3dealer`'s actual `storefront.*` translation usage: `shop.price_min`, `shop.price_max`, `shop.reset` (the price-filter sidebar's min/max labels and its reset link). Picked up by `InstallLunarCommand`'s existing per-key upsert — re-running `lunar:install` on an already-installed store adds only these three rows, leaving everything already seeded or admin-edited untouched.

+# Product Recommendations
+
+`Modules\Core\Catalog\Services\RecommendationService` computes "related products" for a given
+product — a same-category pick today, with a random fallback, but built as a configurable chain of
+strategies rather than one hardcoded rule. `Modules\Core\Catalog\Services\ProductIndexer` embeds
+the result directly into each product's own Meilisearch document, so a product detail page renders
+its recommendations with zero extra queries — same reasoning as `collections` (see
+`docs/product-listing.md`).
+
+---
+
+## The rule chain
+
+```php
+use Modules\Core\Catalog\Services\RecommendationService;
+
+$recommendations = app(RecommendationService::class)->recommend($product, limit: 4);
+// Illuminate\Support\Collection<int, Lunar\Models\Product>
+```
+
+`recommend()` walks `config('catalog.recommendation_rules')` in order, **topping up** from each
+successive rule until `$limit` distinct products are collected or every rule is exhausted — it does
+not stop at the first rule that returns *something*. If a product's category only has 3 other
+products, `SameCategoryRule` contributes those 3 and `RandomRule` fills the last slot. A rule is
+handed the ids already collected (`$exclude`, always including the source product's own id) so it
+never wastes its own `$limit` budget re-suggesting something already picked, and the same product
+is never returned twice even if two rules would both suggest it.
+
+Default chain (`config/catalog.php`):
+
+```php
+'recommendation_rules' => [
+    SameCategoryRule::class,   // other products sharing $product's first collection
+    RandomRule::class,          // universal fallback — always returns something as
+                                 // long as the store has more than one product
+],
+```
+
+A consuming app publishes and edits this config to reorder, add, or remove rules — nothing about
+the chain shape is hardcoded in `RecommendationService` itself. A new rule (same tag, best sellers,
+"frequently bought together", ...) is a class implementing `Modules\Core\Catalog\Contracts\
+RecommendationRule`, added to the array:
+
+```php
+interface RecommendationRule
+{
+    /**
+     * @param  array<int>  $exclude  ids to never return — the source product's own
+     *   id, plus every id an earlier rule in the chain already picked
+     * @return Collection<int, Product>  at most $limit products
+     */
+    public function recommend(Product $product, int $limit, array $exclude): Collection;
+}
+```
+
+Rules query Eloquent directly (`$product->collections->first()->products()`, `Product::query()`),
+not `Modules\Core\Catalog\Services\ProductService` — see "Why not `ProductService`" below.
+
+---
+
+## Why not `ProductService`
+
+Every other read path in `Modules\Core\Catalog` goes through `ProductService`, which reads
+Meilisearch and resolves translated fields to whatever locale the *current request* is in (see
+`docs/product-listing.md`, "Locale resolution"). Recommendation rules deliberately don't use it:
+they run inside `ProductIndexer::toSearchableArray()`, at **index time** — there is no request, no
+meaningful "current locale" to resolve against, and Meilisearch itself may be mid-write for the very
+product being indexed. Rules return raw `Lunar\Models\Product` models instead; `ProductIndexer`
+resolves what it embeds (`name` via `translateAttribute()`, `price` via the indexer's own
+`cheapestPrice()`, `image` via its own `mapMedia()`) the same way it already does for the embedded
+`collections` field — including that field's same accepted index-time-locale tradeoff (a
+recommendation's embedded `name` reflects whatever locale was active when *that* product was last
+indexed, not the viewer's current locale).
+
+---
+
+## What's embedded, and why not just an id
+
+`ProductIndexer` embeds full card data per recommendation, not just an id:
+
+```php
+$data['recommendations'] = [
+    ['id' => 42, 'name' => 'Espresso Cup', 'price' => 12.5, 'image' => 'https://.../thumb.jpg'],
+    // ...
+];
+```
+
+This shape is deliberately exactly what `x-ui.product-card`/`x-product-grid` (3dealer's storefront
+components) need — `name`, `price`, `image`, and an `id` the view resolves to a URL itself via
+`route('product.show', ['id' => $rec['id']])`. A resolved `href` is **not** embedded: `product.show`
+is locale-prefixed (`{locale}/products/{id}`), so a URL baked in at index time would be correct only
+for whichever locale happened to be active during that index run — wrong for every other locale.
+Building the URL is left to the view, which knows the current request's locale.
+
+`recommendations.id` is marked **filterable** — not for the storefront, but for the reverse-lookup
+reindexing below.
+
+---
+
+## Keeping it fresh: `ProductSaved` / `ProductDeleted`
+
+A recommendation is computed once, at index time, and embedded — it does not update itself when the
+recommended product later changes name, price, or image, or is deleted. Unlike `Modules\Core\Catalog\
+Observers\ProductOptionReindexObserver`'s equivalent problem (which product option value is used by),
+there is no Postgres relation for "which products currently recommend product X" — a recommendation
+only exists inside Meilisearch. The fix is a reverse Meilisearch filter query, not a database join,
+wired through a real event → listener pair (`Modules\Core\Providers\CatalogServiceProvider`):
+
+- `Product::saved()` dispatches `Modules\Core\Catalog\Events\ProductSaved`.
+- `Product::deleted()` dispatches `Modules\Core\Catalog\Events\ProductDeleted` — fires for both a
+  soft delete and a force delete (`Lunar\Models\Product` uses `SoftDeletes`), the same model event
+  Laravel Scout's own `ModelObserver` hooks to make a deleted product `unsearchable()`.
+- `Modules\Core\Catalog\Listeners\ReindexProductsRecommendingProduct` handles both: it searches the
+  product index for `recommendations.id = "{id}"`, finds every referencing product, and calls
+  `->searchable()` on each — which recomputes their `recommendations` field fresh, picking up the
+  changed name/price/image, or (for a delete) dropping the now-gone product and topping back up to
+  the configured limit via the rule chain, same as any other reindex.
+
+`->searchable()` dispatches Scout's own reindex job, queued if `SCOUT_QUEUE` is configured — this
+listener does no synchronous Meilisearch writing itself.
+
+**Product creation is deliberately not hooked into this.** A brand-new product has no
+`recommendations` of its own until Scout's existing create-triggered indexing runs (already correct
+— nothing to add). What's *not* immediate is other products picking the new one up as a fresh
+recommendation candidate — that happens on their own next natural reindex (a save, or the nightly
+full reindex below), the same accepted staleness window `docs/product-listing.md` already documents
+for `in_stock`/`price`. A full proactive "who could now recommend this new product" pass was
+considered and rejected as unnecessary cost for a cosmetic delay.
+
+---
+
+## Nightly full reindex
+
+`Modules\Core\Providers\CatalogServiceProvider` schedules `lunar:search:index "Lunar\Models\Product"
+--refresh` daily at 03:00 — a safety net on top of the event-driven reindexing above, not a
+replacement for it. Catches what event-driven reindexing deliberately doesn't cover: a newly-created
+product not yet appearing as a recommendation elsewhere, and any other drift already accepted
+between reindexes (see `docs/product-listing.md`, "Stock goes stale between orders"). `--refresh`
+also re-syncs filterable/sortable index *settings*, not just documents, so a deploy that changed
+`ProductIndexer`'s field list self-heals overnight even if `lunar:meilisearch:setup` wasn't run
+manually right after that deploy.
+
+---
+
+## Re-syncing after this change
+
+Same as any other `ProductIndexer` field change (see `docs/product-listing.md`):
+
+```bash
+php artisan lunar:meilisearch:setup
+php artisan lunar:search:index "Lunar\Models\Product" --refresh
+```
+
+Restart the queue worker if `SCOUT_QUEUE=true` — see `docs/product-listing.md`'s "Re-syncing after
+this change" for why a running worker won't otherwise pick up the new indexer code.
