Follow-up to #20958. The worker skill section had the same stale
'hermes skills install devops/kanban-worker' command — kanban-worker
is also bundled, so that command fails with 'Could not fetch from any
source.'
Replace with bundled-skill verification + restore pattern, matching
the orchestrator section. Uses <your-worker-profile> placeholder since
assignees vary (researcher, writer, ops, linguist, reviewer, etc.)
rather than a single fixed 'worker' profile.
