agentHealth.tsx:
- Drop the "Disabled" label and isHeartbeatEnabled helper. Server-side
heartbeat scheduling is driven by agent.state (active/running = armed),
not by the legacy runtimeConfig.enabled flag, so surfacing "Disabled" for
agents with a stale flag on disk was misleading.
- Replace the elapsed > heartbeatTimeoutMs check with elapsed > 2× effective
interval (with a 60s floor). heartbeatTimeoutMs is the per-run work budget,
not a between-tick freshness window; using it made any agent configured
with a multi-minute+ interval show Unresponsive the moment it got more
than 60s old. The effective interval resolver now falls back to the
server-side 1h default, so agents never configured via the dropdown and
agents with an explicit interval get consistent treatment, differing only
by scheduled cadence.
AgentDetailView.tsx:
- Remove Stop buttons from active/paused/running/error (mirrors the earlier
AgentsView cleanup — Pause/Resume/Retry cover reversible transitions,
Delete stays on idle/terminated for teardown).
- Add a "Next Heartbeat" info row alongside "Last Heartbeat" for ticking
agents (active/running), computed as lastHeartbeatAt + effective interval.
Tests rewritten to cover the new semantics; dropped 14 obsolete cases that
were pinned to the old heartbeatTimeoutMs-based check and the "Disabled"
branch. 42 agentHealth tests pass.
