5eec01a9d6 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

e1ee79a386 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.

c2f2d10ee1 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)
