Root-cause fix for "we hit launch, waited overnight, nothing ran."
mission_orchestrator materialized teams + agents fine, but nothing
enqueued the actual work — mission_phases stayed 'pending' forever
and topology_runs count for the mission was 0.
New crates/cm-api/src/phase_runner.rs — background worker on 10s
poll that does three things:
1. start_pending_phases — for every mission_phase with
status='pending' AND parent mission.status='running' AND all
lower-order phases already 'completed', enqueue one
topology_runs row per team whose (mission_id, purpose) matches
the phase kind:
phase=research → teams with purpose='research'
phase=coding → teams with purpose='coding'
phase=benchmark → teams with purpose='coding' (fallback)
phase=security_scan → teams with purpose 'security' | 'coding'
Each run gets a phase-kind-specific task text combining the
mission title/description + a directive for that phase.
Flips phase to 'running' after enqueue.
2. close_finished_phases — SQL sweep that flips phases whose
topology_runs are all terminal to 'completed' (or 'failed' if
any run failed).
3. close_finished_missions — same shape for missions whose phases
are all terminal.
Spawned alongside task_card_worker in clawmates-server main.rs.
Ordering enforced by mission_phases.order_idx — a coding phase
doesn't fire until its research phase completes.
Idempotent: every state transition is guarded so double-firing on a
race is safe. When a mission has no matching teams for a phase (bad
wizard state), the phase stays pending and the runner logs a skip
rather than getting stuck in a fail loop.
Existing topology_worker picks up the queued runs and drives them
through the ZeroClaw executor as usual.
