feat: default_label_resolver reads name property; item-template convention

The default label_resolver now reads the optional player-facing `name`
property from the item-template; modules with named templates get pretty
row labels without registering an override. Falls back to "Item" when
`name` is absent or empty.

README documents the player-facing item-template convention: name,
description, weight, volume, composition.<material> — all optional,
all with documented defaults. Skill-gated description reveals stay on
the separate hints lib (designed, not yet implemented).

+## Item-Template-Convention
+
+This widget reads optional player-facing properties from the item's
+composition-template. All are optional; missing values fall back to
+defaults.
+
+| Property | Type | Default | Used by |
+|---|---|---|---|
+| `name` | string | template-id-fallback / `"Item"` | default `label_resolver` — shown in the row |
+| `description` | string | (empty) | consumer-side actions (e.g. Inspect) — flavor text |
+| `weight` | number | 0 | reserved — read by `inventory-grid` (Phase F/G) |
+| `volume` | number | 0 | reserved — read by `inventory-grid` (Phase F/G) |
+| `composition.<material>` | number (0-1) | (absent) | crafting recipes (Phase E); see `architecture/composition-model.md §4` for material catalog |
+| `sprite_atlas` | string | (empty) | default `icon_resolver` — atlas path for icon |
+| `sprite_uv` | `{x,y,w,h}` | (absent) | default `icon_resolver` — UV rect within atlas |
+| `stack_mode` | string | required by `inventory-list` | `"individual"` only in v0.x |
+| `position.x/y` | number | required for world placement | rendered by `lib-core.render` |
+
+**Skill-gated reveals on top of `description`** are handled by a
+separate `lib-core.hints` lib (designed, not yet implemented). When
+hints land, the base `description` stays untouched; hints attach
+predicate-gated extra reveals at examine/tooltip time. Modules without
+skill systems use `description` as the only flavor text.
