browser relay: multi-session override, stale session recovery, better error feedback
- relay accepts new extension connections by closing old one (last wins, code 4000) - extension recognizes code 4000 and stops auto-reconnect (shows "replaced" badge) - fix ping interval race where old WS close handler killed new connection's pings - retry CDP commands on "Session with given id not found" by re-attaching debugger - describeError() maps known errors to user-friendly badge tooltips - persisted relay tokens restored on server start - user-scoped token salts, token regeneration/deletion endpoints - extension download endpoint, integrations UI for browser relay setup - browser relay env vars passed to pi-bridge sandboxes - browser screen layout with chat panel and prompt prefix Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
