v0.12.55+12055-macos

## OMI Desktop v0.12.55

### What's New
- Hardened screen-aware agent launches, tool schemas, and realtime tool error reporting.
- Improved desktop chat screen-context detection and diagnostics
- Background agent chat links now reopen from the timeline even after pills dismiss
- Fixed Background agent cards so the header collapses again, markdown renders in the expanded body, and the open-agent link hides when the agent is unavailable
- Fixed floating bar treating block-only or artifact answers as failed empty responses
- Fixed silent agent-link opens and restored background-agent chat continuity after pills dismiss
- Fixed a main-thread freeze where chat text selection wrapped agent card headers and pegged CPU
- Show typed notch, notch PTT, and spawned-agent link turns in the shared Omi chat history
- Background agent cards and proactive notifications now stay consistent across chat surfaces after reload
- Fixed continuity review findings: restage can create a missing assistant after a user-only stage, owner-swap clear no longer clobbers a mid-session auth uid, agent open ordering is generation-guarded, and agent cards hide dead Open links / avoid false-success status icons
- Floating bar chat now reads from the shared chat timeline instead of keeping a separate copy
- Attach Gemini push-to-talk screen frames immediately after activity start instead of at commit so current-screen questions have time to ground on the image
- Send Gemini push-to-talk screen frames inside the active voice turn before commit so screen questions ground on current pixels instead of a too-late screenshot tool call
- Fixed Home chat input focus after expansion and added Escape-to-Home navigation on secondary Home pages
- Polished the desktop Home stage layout, wider chat surface, responsive ask bar, and icon-only notch thinking state
- Fixed notch and chat so agent artifacts stay attached to the turn that produced them, old orphan artifact cards no longer appear in the floating viewport, and agent list/card previews show the prompt instead of the response
- Fixed a test-owner swap that could wipe sign-in tokens and break chat loading until relaunch
- Make push-to-talk screen context fresher and less brittle by prefetching canonical voice-turn screen context while the user speaks and preventing stale screenshot OCR from biasing transcript correction
- Made push-to-talk screen context prefer live capture when finalized screen frames are more than a few seconds old
- PTT now tries available Omi context before asking follow-up questions and delegates larger work to background agents when a short voice answer is not the right surface
- Fixed duplicate chat messages after push-to-talk
- Buffered push-to-talk screen context until realtime sessions are ready so cold starts and reconnects do not drop it
- Fixed subagent chats so completed agents show their final output and stop showing stale Running or Working indicators
- Keep main chat subagent links visible without showing completed implementation-only tool logs, and keep externally spawned agent pills synced to terminal runtime state
