NEO-74: Address code review — recipe sync HUD and test uids.

Wire recipes_sync_failed to CraftFeedbackLabel, remove unused _scroll
binding, add GdUnit .uid companions, extend recipe client HTTP error
test, strike through review items.

 **Date:** 2026-05-24  
 **Scope:** Branch `NEO-74-e3m2-client-craft-ui-recipe-list` · commits `dff58ad`–`c16b610` vs `origin/main`

+**Follow-up:** Review feedback addressed (recipe-sync failure HUD, test `.uid` companions, unused `_scroll` binding).
 
 ## Verdict
 
-**Approve with nits** — implementation matches the adopted plan and E3S5-03 acceptance criteria; all nine new GdUnit cases pass headless. Remaining items are non-blocking (test `.uid` companions, optional recipe-sync failure HUD).

-1. **Wire `recipes_sync_failed` in `main.gd`** — `RecipeDefinitionsClient` emits **`recipes_sync_failed`** (tested in GdUnit) but **`main.gd`** never connects it. On boot failure the recipe panel stays empty with no HUD line (inventory/skill clients show errors). Connect to **`CraftFeedbackLabel`** or **`push_warning`** + a one-line error for parity with **`inventory_sync_failed`** / **`progression_sync_failed`**.

 ## Nits
 
-- Nit: **`craft_recipe_panel.gd`** declares **`@onready var _scroll`** but only uses **`_vbox`** — remove unused binding or use **`_scroll`** for max-height policy.

 - Nit: **`craft_feedback_refresh_test.gd`** harness duplicates refresh logic from **`main.gd`** (intentional isolation) — acceptable; no **`main.gd`** integration test remains (same gap as NEO-73 gather refresh test).
