Implements a stale heartbeat reaper in the engine that detects and cleans up heartbeat runs exceeding their timeout, preventing blocked heartbeat cycles from stalling agent activity. Includes comprehensive tests for the reaper gates and documentation of the feature in agents.md.
Fusion-Task-Id: FN-4119
Adds stale timer repair handling to the heartbeat scheduler with test coverage, and updates the agents documentation accordingly.
Fusion-Task-Id: FN-4033
Adds health-surfacing logic for timer-triggered stale heartbeats in the engine, a new `agentHealth.tsx` dashboard utility with tests, and documentation updates for the repair behavior.
Fusion-Task-Id: FN-4020
Adds scheduler heartbeat timer reconciliation with automatic self-healing when timers drift, including tests for tracked-only monitor recovery and documentation in the agents reference.

This merge restores the canonical agent lifecycle with termination scoped at the run level (FN-3580, 4 steps), adds sender-side wake recipient override for messages, and introduces test isolation CI enforcement with a stuck-requeue race fix. UI changes remove terminated-agent indicators from AgentDe

This merge completes the agent terminated state alignment (FN-3535), adding "running → terminated" transition support with consistent styling and lifecycle controls across the heartbeat engine, agent store, and dashboard UI, plus plugin author documentation improvements (FN-3537) and plugin loader t

Permanent agents now run heartbeats regardless of bound-task block state.
The prior queued+blockedBy early-exit and its state-tracking machinery are
removed; HEARTBEAT_SYSTEM_PROMPT is rewritten to scope heartbeats to
ambient coordination (messaging, memory, finding work, delegation,
surfacing/chasing blockers, status). Task body work continues via the
executor path. Ephemeral agents are unchanged.
New allowParallelExecution flag (default true, permanent agents only) on
AgentHeartbeatConfig. When false, heartbeat and executor paths serialize
symmetrically: a heartbeat will not start while the agent's bound task
has an active executor session, and an executor session will not start
while the agent has an active heartbeat run. Either side re-dispatches
the other's deferred work on completion. UI toggle surfaces in the
agent's Heartbeat Settings tab.

When a permanent agent has allowParallelExecution=false, TaskExecutor.execute()
defers if the agent has an active heartbeat run, and HeartbeatScheduler defers
a heartbeat if the agent's bound task has an active executor session. Each side
re-dispatches the other's deferred work on completion via resumeTaskForAgent
and the in-process runtime's onRunCompleted hook.

Drops "terminated" from AGENT_STATES. The agent lifecycle now runs through
idle | active | running | paused | error. paused (carrying a pauseReason)
absorbs every former terminated use case — manual stop, heartbeat run
termination, spawned-child cleanup. Run status (agentRuns.status) is
unchanged: "terminated" stays a valid run-status value.
AGENT_VALID_TRANSITIONS allows direct any→idle transitions so resetAgent
no longer needs the intermediate hop.
Stack-wide:
- core/agent-store: lastError clearing + resetAgent simplified.
- engine/agent-heartbeat, executor, in-process-runtime: terminated state
writes → paused; halt-state listener fires on paused/error.
- dashboard: AgentsView/AgentListModal/AgentDetailView lose the Terminated
badge/option/state-block; agent pickers no longer filter terminated;
agentHealth drops the Terminated branch; routes/state cast widened to
the new AgentState union.
Tests across core and engine updated to assert paused for AgentState and
left "terminated" intact for run-status assertions.

Fixes CSS token consistency issues in TaskDetailModal and SettingsModal, and updates the corresponding mobile overflow test to match the refactored styles.
