- applications.mjs: import HandlebarsApplicationMixin/ApplicationV2 from
foundry.applications.api (they are not globals in Foundry v14), fixing
'ReferenceError: HandlebarsApplicationMixin is not defined'
- Replace activateListeners(html) with _onRender(context, options) and
this.element — AppV2 does not call activateListeners
- TraitSelector: remove recursive render(true) in _validateTraits
- fight.mjs: VermineCombatTracker same _onRender conversion
