Address remaining review feedback: 1) Add HistoryTokens field to ContextUsage/ContextStats, showing history-only token count in /context and frontend UI alongside SummarizeAtTokens so users can see the actual summarization trigger comparison. 2) Remove .codebuddy/github-contribute/ state files accidentally included in the PR.
* feat: add request-scoped context policies
Add named turn profiles under agents.defaults so callers can opt into
per-request context and tool policies without changing default chat behavior.
Profiles can disable history, system context, skill prompts, or tools, and can
limit skills/tools with allow lists. Wire profile selection through Pico message
payloads, agent turn execution, Web chat selection, and Web visual config.
Reject invalid turn profiles before saving config through Web APIs and document
the new request context policy behavior.

* feat(web): download attachments in frontend
* fix: proxy pico media and force svg downloads
* feat(web): hide ephemeral media refs from persisted session history
* perf(pico): implement O(1) session lookup for pico connections
- Replace `sync.Map` with `connections` and `sessionConnections`.
- Add `addConnection`, `removeConnection`, `sessionConnectionsSnapshot`, and `takeAllConnections` with `connsMu` for concurrency.
- `broadcastToSession` now dispatches directly to `sessionConnections`.
- Add `newUniqueConnID` to avoid UUID collision/overwrites.
- Ensure `Stop` and `readLoop` use the new helpers for safe cleanup and correct `connCount` updates.
* refactor(pico): replace addConnection with createAndAddConnection for atomic connID generation
* refactor(pico): clear connections in one time to improve perf

* fix(pico): keep connCount consistent with connection indexes
* refactor(pico): make connCount a regular int guarded by connsMu
* fix(pico): enforce MaxConnections atomically on registration
* fix(pico): use temporary over-limit error and remove conn counter
