Track lib-core.panel v0.2.0 (multi-active panels with layout-slots).
No behavioral change in this consumer — the v0.1.1 call sites remain
compatible via the panel framework's bw-compat shim.

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).
5 public functions (create, register_action, unregister_action,
set_label_resolver, set_icon_resolver) plus 2 test backdoors
(_test_get_rows, _test_resolve_icon). Reads lib-core.inventory-list
contents each render frame; right-click rows open context-menu via
panel.show_context_menu. Default action-set is empty.
