feat: v0.12.0 Workbench-Integration

Workbench-Entity bei (350, 380) als Crafting-Context-Erweiterung.
Right-Click oeffnet Workbench-Crafting-Panel + Workbench-Inventory.
Crafting nutzt Multi-Source-Locale {backpack, workbench} mit sink
= workbench; Take-Action verschiebt vom Workbench-Inventory zum
Backpack. C-Key Backpack-Crafting bleibt unveraendert via Bw-
Compat-Shim in crafting v0.2.0.

Deps: crafting 0.1.0 -> 0.2.0, crafting-display 0.1.0 -> 0.2.0.

 ## CHANGELOG
 
+### v0.12.0 — Workbench
+
+- **New: Workbench entity** in the world at (350, 380) — `composition.define_template`
+  with `container = {kind="list"}`, tagged `renderable`, `container`, `workbench`,
+  `interactable`. Placeholder visual re-uses the `slot_07_tee_full`
+  blob_rect_stone tile (visually distinct from rock/stick/rock_pick/rock_pile).
+- **New: Right-Click on Workbench** opens two panels:
+  - **Workbench Crafting** — recipes are still listed by `lib-core.crafting`,
+    but availability + craft-action use a **multi-source locale**
+    `{sources={backpack, workbench}, sink=workbench}` (crafting v0.2.0 API).
+    Inputs are drained greedy in source-array order (backpack first, then
+    workbench). Output lands in the Workbench, not the Backpack.
+  - **Workbench Inventory** — workbench contents with **Take** + **Inspect**
+    actions on right-click. Take moves the item to the Backpack and fires
+    a `transfer` event-toast.
+- **Still works**: C-key Backpack-Crafting (basic recipes still craftable
+  with Backpack-only via the bw-compat shim in crafting v0.2.0). The
+  Phase-C C-key callsite passes `state.backpack` as a bare entity-handle;
+  crafting v0.2.0's resolve_locale wraps that as `{sources={backpack},
+  sink=backpack}` transparently.
+- **Caveat (panel-lib v0.1 single-active)**: `lib-core.panel` v0.1.1
+  enforces one active widget. Opening both Workbench panels means only
+  the second (`workbench_inv`) is visible until the player closes it (X);
+  closing it reveals `workbench_crafting`. Proper side-by-side stacking
+  is a future panel-lib slice.
+- **Deps**: crafting 0.1.0 → 0.2.0, crafting-display 0.1.0 → 0.2.0.
+- **Notify events-Channel**: filter um `"transfer"` erweitert, damit
+  Take-Action-Toasts im events-channel landen.
+- **Input binding**: `"use"` bound to `mouse_right` (mirrors the lib-core.input
+  v0.3.0 unified key+mouse binding).
