When downloading HTML artifacts, the generated HTML now works standalone
without requiring the extension runtime.
Changes:
- Add PrepareHtmlOptions config object to SandboxedIframe.prepareHtmlDocument()
- Add isStandalone flag to skip runtime bridge and navigation interceptor
- When isStandalone=true:
- window.sendRuntimeMessage is NOT defined
- Navigation interceptor is NOT injected
- Artifact runtime providers fall back to embedded data
- HtmlArtifact download button now uses isStandalone: true
This fixes the issue where downloaded HTML artifacts would:
- Try to call window.sendRuntimeMessage (which would fail silently)
- Try to postMessage to non-existent parent window
- Not work when opened via file:// protocol
Now downloaded artifacts work completely standalone with embedded data.
- 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.
- Add 'aborted' as a distinct stop reason separate from 'error'

- Map provider-specific safety/refusal reasons to 'error' stop reason
- Reorganize utility functions into utils/ directory

- Export Type and Static from main package for convenience
- Update all tests and documentation to reflect TypeBox usage
- Replace JSON Schema with Zod schemas for tool parameter definitions
