BeadClaimed fires on successful claim with source=beads/<mount> and
data={bead_id, assignee, mount}.
Worker roles (developer, devops, pkgmgr, researcher, tester, author)
now have a Bead Loop section: wait_for_bead.sh → claim → work →
complete → repeat. Reviewer role is spawned by workers, not looping.
