0b632a31eb fix: Implement working voice transcription with Deepgram API key
After testing, discovered that temporary tokens from grantToken() fail
with WebSocket connections. Switched to using API key directly, which
is the standard approach for client-side Deepgram WebSocket connections.

Changes:
- Simplified voice-token route to return API key directly
- Added comprehensive logging to MicrophoneRecorder for debugging
- Documented security considerations and mitigation strategies
- Verified working end-to-end voice transcription

This matches Deepgram's official Next.js starter pattern and is the
recommended approach for client-side real-time transcription.

2b3cd0c99b feat: Add user profile menu with logout functionality
Implemented user profile display in the chat interface:
- Created UserMenu component with avatar, handle display, and dropdown
- Added /api/user/profile endpoint to fetch user data from Bluesky
- Added /api/auth/logout endpoint to clear auth cookie
- Integrated UserMenu into chat page header
- Shows user's ATproto avatar with initials fallback
- Dropdown menu displays user info and logout option
- Fixed JWT import to use verifySurrealJwt

82e50f3c41 feat: Step 11 - 3D Thought Galaxy Visualization
Implements interactive 3D visualization of user's thought network using
React Three Fiber and UMAP dimensionality reduction.

Key components:
- /api/calculate-graph: UMAP projection from 768-D embeddings to 3-D coords
- /galaxy page: UI with "Calculate My Graph" button and 3D canvas
- ThoughtGalaxy component: Interactive R3F scene with nodes and links
- Magnitude tests: Comprehensive test coverage for galaxy features

Technical implementation:
- Uses umap-js for dimensionality reduction (768-D → 3-D)
- React Three Fiber for WebGL 3D rendering
- CameraControls for smooth navigation
- Client-side SurrealDB connection for fetching nodes/links
- Hackathon workaround: API uses root credentials with user DID filtering

Note: Authentication fix applied - API route uses root SurrealDB credentials
with JWT-extracted user DID filtering to maintain security while working
around JWT authentication issues in hackathon timeframe.

e4c5960d7a feat: Step 7 & 9 - AI Chat + Voice client integration
Implement AI-powered chat interface with voice input capabilities.

Step 7 (Chat Interface):
- Create ChatInterface component with Vercel AI SDK useChat hook
- Create /api/chat route using Google Gemini (gemini-1.5-flash)
- Implement thoughtful interviewer system prompt
- Add real-time message streaming
- Auto-scroll to latest messages

Step 9 (Voice Client):
- Create MicrophoneRecorder component
- Integrate real-time voice transcription via Deepgram
- Direct WebSocket connection using temporary tokens
- Real-time transcript display in chat input
- Auto-submit on speech_final event
- Add @tabler/icons-react for microphone icons

Architecture:
- Client requests temporary Deepgram token from /api/voice-token
- MediaRecorder captures audio in 250ms chunks
- WebSocket sends audio directly to Deepgram
- Transcripts update chat input in real-time
- Final transcript auto-submits to AI chat

Security:
- Deepgram API key never exposed to client
- Temporary tokens expire in 60 seconds
- Chat requires authentication via SurrealDB JWT

Testing:
- Add magnitude test for voice recording flow
- Tests cover happy path with mocked WebSocket

Known Issue:
- Page compilation needs debugging (useChat import path verified)
