refactor(agents): remove terminated AgentState; collapse to paused/error

Browse Source 
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.

Remove the `terminated` AgentState. The agent lifecycle now runs through `idle | active | running | paused | error`, with `paused` (carrying a `pauseReason`) absorbing every former `terminated` use case (manual stop, heartbeat run termination, spawned-child cleanup). Run status is unchanged — heartbeat runs still report `terminated` independently of the agent state.
Migration: existing `agents` rows where `state = 'terminated'` are rewritten to `state = 'paused'` with `pauseReason: 'migrated-from-terminated'` on first store init (`__meta` key `removeTerminatedAgentState`). The dashboard "Terminated" filter option, badge, and CSS rules are gone; "Stop" buttons now transition the agent to `paused`. The `dashboard.READMEs` "Terminated agent filtering" behavior in the agents list is also dropped — paused/error agents are visible by default, and AgentListModal/AgentsView no longer hide them in "All States."
