Beads pane

Three sections: Ready (bd ready), Claimed (bd list --status in_progress) and Touched this session (ids from Bash calls that ran bd update, close, claim or reopen). The bead the session claimed last is marked and pinned on the status line as bead: <id> <title>.

It reads bd on /beads and /beads refresh, after a Bash call that ran a bd write, and on an opt-in poll. Each read uses a fixed argv (no shell) with a 4 s timeout. The mod never runs a bd command that writes.

With no .beads folder, /beads says so and bd never runs. When bd is missing, slow or fails, the pane says which command failed; bd’s stderr is never shown.
