Synced from monorepo

Changes:
- Release a shell session's resources in one drop
- Make the tools blocking-wait cap client-configurable and self-describing
- Recognize API "exceeds budget" errors as context overflow
- Retry /btw on model overload
- Carry running background tasks and subagents across compaction
- Require round-trip time for SDK liveness checks
- Background-subagent completion reminders with a selectable delivery surface
- Make a PTY shell reap itself until it reaches the registry
- Recover the OS error code from a TLS-phase connection reset
- Consume the attached-client signal and report why idle is withheld
- Treat `.grok/sandbox.toml` edits as protected so auto mode prompts before writing
- Surface history/search in the Ctrl+. cheatsheet and keep it working in history view
- Delete sessions from the dashboard and welcome list
- Release a session's activity record when the session ends
- Stop charging auth-retry budget for fail-closed 401s; reset it across suspends
- Scope skills watches on project vendor roots
- Make [stop] cancel in-flight compaction
- Make the leader soak measure the leader, not its harness
