- Add `SEARCH_PROVIDER` config with Tavily/Brave API key validation in server and prod script
- Introduce unified `web_search` tool and shared search service with Tavily + Brave backends
- Update chat UI tool status/result labels to treat both search tools consistently
Add user profile page with custom avatar upload (crop/resize to 256px),
avatar display throughout the app, and MD5-based Gravatar fallback.
Add image paste/attach support in chat with vision model detection via
OpenRouter API. Images can be pasted from clipboard or selected via file
picker, uploaded to the server, and sent alongside messages. The AI
receives images as base64 data URLs for multimodal models. Models with
vision support are indicated with a badge in the model picker.

Replaces batch AI responses with real-time SSE streaming from OpenRouter.
Tokens are buffered client-side and drained via requestAnimationFrame for
a smooth typing effect instead of choppy chunk dumps.
Backend:
- Rewrite openrouter service for SSE streaming with incremental tool call accumulation
- Add AiStreamChunk/AiStreamEnd WebSocket event types
- Stream content deltas to clients during all tool call rounds
- Increase broadcast channel capacity (256 -> 4096) and handle Lagged errors gracefully
Frontend:
- Add StreamBuffer utility with adaptive rAF-based character draining
- Show streaming message-bubble with blinking cursor during generation
- Clean up buffer on room switch and final message replacement
