Heartbeat service now resolves session state per-task using agentTaskSessions,
with resolveNextSessionState handling codec-based serialization and fallback
to legacy sessionId. Queued runs are chained — when a run finishes or is reaped,
the next queued run for the same agent starts automatically. Queued runs for
an agent with an already-running run wait instead of failing.
Add task-sessions list endpoint and extend reset-session to accept optional
taskKey for targeted session clearing. Block pending_approval agents from
API key auth. Update agent/company delete cascades to include task sessions.
Update spec docs with task-session architecture.
