- Implement JS-rendered page detection for sites like docs.rs
- Add chromedp dependency for headless browser support
- Log fetch method on server startup
Frontend:
- Store tool results in structured ToolCall.result field instead of message content
- Show tool results collapsed by default in ToolCallDisplay
- Add expandable results section with truncation for large outputs
- Add Message.hidden flag for internal messages (tool context)
- Separate visibleMessages (UI) from allMessages (API) to fix infinite loop
- Fix tool result messages not being sent to model

- Add /api/v1/location endpoint using ip-api.com for IP geolocation
- Update get_location tool to try browser GPS first, then IP fallback
- Make tool description directive to trigger automatic usage
- Handle private IPs by letting ip-api.com auto-detect
The tool chain now works: get_location → web_search → fetch_url
Browser geolocation often fails on desktop Linux; IP fallback
provides city-level accuracy which is sufficient for weather queries.
