fix(deploy): resolve SQL timeouts, YAML drift, and orphaned tmux sessions

- lib.sh: update atomic_dump_yaml to sync with YAML on any active session status change; set reader timeouts to 60.0s
- create_session.sh: add exit trap cleanup_tmux_on_error to rollback spawned tmux sessions on initialization failures
- reconcile.sh, update_yaml_resumed.sh, status.sh, stop_session.sh: align SQLite connection timeout values to 60.0s
