- Fix undefined 'npc' variable in applications.mjs
- Fix CONFIG.VERMINE.model undefined by checking game.system.template existence
- Fix TypeError: html.find(...).forEach is not a function in roll.mjs
- Fix Cannot set properties of undefined (setting 'initial') in actor.mjs
- Fix Cannot read properties of undefined (reading 'difficulty') in actor.mjs
- Fix ActiveEffect application phase 'initial' already completed by adding combatStatus to base template
- Fix Missing helper: 'select' in roll-dialog.hbs (removed invalid Handlebars select block)
- Add SIZE_LEVELS labels to creatureSizeLevels config
- Add SIZE_LEVELS translations to fr.json
- Add combatStatus to base actor template
- Convert all .html templates to .hbs for Foundry v14 compatibility
- Update item-sheet.mjs to use .hbs extension
