feat: lib-core.crafting-display-test v0.1.0 — 8 TAP asserts
Test suite for lib-core.crafting-display v0.1.0. Covers:
1. create returns widget_def with render, handle_input, title set
from opts.
2. register_action + unregister_action round-trip: action-count
goes 0 -> 1 -> 0.
3. Duplicate action label -> Loud-Error matching
'crafting-display.register_action.*duplicate'.
4. Non-function callback -> Loud-Error matching
'crafting-display.register_action.*callback'.
5. Default action-set is empty directly after create.
6. Rows filtered via is_known: only known recipes appear in the
per-frame row-list (one recipe is_known=false is hidden).
7. Per-row availability flag matches can_craft.ok: container with
1x rock makes a recipe needing rock available=true and a
recipe needing missing stick available=false.
8. Resolver overrides (set_icon_resolver / set_label_resolver /
set_summary_resolver) actually take effect — backdoors return
the overridden values.
Uses engine.test.assert with string.find for pattern matching
loud-error messages (engine.test has no assert_match helper).
Per-test isolation via crafting._test_clear_all; composition
templates are defined once at module-scope under namespace
craft_display_test.* (composition has no clear-all hook).
Depends on lib-core.crafting-display 0.1.0, lib-core.crafting
0.1.0, lib-core.panel 0.1.1, lib-core.inventory-list 0.1.0,
lib-core.composition 0.3.0 — all five declared directly per
engine's per-module non-transitive resolver.
