- Changed ToolRenderer return type from TemplateResult to ToolRenderResult
- ToolRenderResult = { content: TemplateResult, isCustom: boolean }
- isCustom: true = no card wrapper, false = wrap in card
- Updated all existing tool renderers to return new format
- Updated Messages.ts to handle custom rendering
This enables tools to render without default card chrome when needed.
- Extract ArtifactsToolRenderer from ArtifactsPanel into standalone renderer
- Fix ChatPanel to register ArtifactsToolRenderer instead of panel
- Implement command-specific rendering logic (create/update/rewrite/get/logs/delete)
- Create reusable Console component with copy button and autoscroll toggle
- Replace custom console implementation with ExpandableSection and Console
- Fix Lit reactivity for HtmlArtifact logs using spread operator
- Add Lucide icons (FileCode2, ChevronsDown, Lock) for UI consistency
- Follow skill.ts patterns with renderHeader and state handling
- Add i18n strings for all artifact actions and console features
