feat(vscode): add full chat interface to OpenClaude extension (#608)

Add a Claude Code-like chat experience to the VS Code extension with:
- Streaming chat panel (sidebar + editor tab) with markdown rendering
- Tool use visualization with inline diffs (replace/with display)
- Session history browser with JSONL transcript parsing
- Thinking block indicator with elapsed time and token count
- Clickable file paths that open in the editor
- Permission mode setting (acceptEdits default)
- Multi-turn conversation support via NDJSON stream-json protocol
- Status bar with live activity indicators
- Ctrl+Shift+L keybinding to open chat panel

Made-with: Cursor
