Tree sync 75e73f3d6ac0 → b13fa526f511: /rename --auto to clear a pinned title and resume auto-titling, plus docs and internal reliability work.
Changelog
[new] /rename --auto unpins a manual session title and lets auto-titling resume (Build sessions only; must be the sole argument)
[changed] Session rename docs cover the new flag and note that a session cannot be named --auto via the command (use the dashboard rename editor for that case)
Agent & tools
/rename (alias /title) accepts --auto to clear a manual title and re-enable auto-titling on Build sessions; chat conversations have no local auto-titler
/rename --auto Something is rejected; use dashboard rename (Ctrl+R) if you need the literal title --auto
Docs
User guide slash-commands and sessions pages document /rename --auto and its constraints
Under the hood
Internal workspace RPC activity-window and blocking-pool / EAGAIN containment knobs for shell and tty-utils runtimes
Dropped unused heck and socket2 lockfile entries
Additional coverage for session rename, agent server paths, spawn-runtime containment, and tty-utils runtime behavior
