* feat: add copy-link button to share viewer messages
Implements the feature requested in #437:
- Add a small link icon button that appears on hovering over user/assistant
messages in the share viewer
- Clicking the button copies a shareable URL to clipboard with visual feedback
- URL format: base?gistId&leafId=<active-leaf>&targetId=<message-id>
- When loading a URL with leafId and targetId params:
- Navigate to the specified leaf node
- Scroll to and briefly highlight the target message
This enables users to share links to specific messages within a session.
* fix: preserve gist ID format and add clipboard fallback
- Fix URL format to produce ?gistId&leafId=... instead of ?gistId=&leafId=...
(preserves the bare key format expected by the backend)
- Add execCommand fallback for clipboard copy on HTTP contexts where
navigator.clipboard is unavailable
- Add optional 'export' section to theme JSON with pageBg, cardBg, infoBg
- If not specified, colors are auto-derived from userMessageBg
- Add export colors to dark.json and light.json
- Update theme-schema.json and TypeBox schema
- Add documentation to docs/theme.md
- Add margin-top back to tool-output for spacing between header and content
- Add theme property to HookUIContext interface
- Implement in interactive, RPC, and no-op contexts
- Add status-line.ts example hook
- Document styling with theme colors in hooks.md
The white-space: pre-wrap on .tool-output was preserving template
literal whitespace (newlines and indentation). The pre elements
inside still have pre-wrap for actual code content.
- Split template into separate files: template.html, template.css, template.js
- Add tree visualization sidebar for session navigation
- Fix HTML sanitization to prevent <style> tags breaking DOM
- Add DOM node caching for faster re-renders
- Fix tree indentation to match tree-selector.ts
- Add /share command to upload session as GitHub gist
- Support shittycodingagent.ai/session?{gistId} URLs
