Pull request overview
Adds end-to-end “headless agent session” tracking and UI so background (non-terminal) agent runs can be listed, monitored, and controlled from the renderer.
Changes:
- Introduces renderer store state/actions for headless sessions (add/update/dismiss/prune + last-output tracking).
- Adds UI for displaying headless sessions above the grid (including an expandable pill with live log streaming), plus settings for visibility and retention.
- Adds IPC + server method support for listing headless sessions and polls/syncs them in the renderer.

Fixed: setHeadlessSessions now rebuilds from the server list, dropping sessions the server no longer reports. Locally-added running sessions (not yet known to server) are preserved. Output entries for removed sessions are also cleaned up.

Fixed: headlessLastOutput entries are now deleted in dismissHeadlessSession, pruneExitedHeadless, and setHeadlessSessions (when sessions disappear from server). headlessDismissed is also cleaned up during pruning.

Fixed: changed opacity-65 to opacity-[0.65] (Tailwind arbitrary value syntax).

Fixed: removed the duplicate inline style={{ animation }} — now only using the Tailwind animate-[borderPulse_...] class.
Headless agents spawned by workflows are now visible in the Sessions view as compact inline pills above the interactive session grid. - Add headless:list IPC to query active headless sessions from server - Track headless sessions in Zustand store with real-time updates - HeadlessPill component: status dot, agent icon, name, branch, live duration timer, exit code badge, expandable log output - Close button hides pill (process continues), Kill button stops process - Auto-prune exited sessions after configurable retention (default 5 min) - Settings: toggle visibility + retention duration in General settings - Project/workspace/status filters apply to headless pills
- Fix phantom sessions: setHeadlessSessions now removes sessions gone from server instead of only merging (keeps locally-added running ones) - Fix memory leak: dismissHeadlessSession and pruneExitedHeadless now clean up headlessLastOutput and headlessDismissed maps - Fix opacity-65 (not a default Tailwind class) to opacity-[0.65] - Remove duplicate inline style animation (keep Tailwind class only)
