* feat(server): release idle agent runtimes with provider safety checks
Require provider permission before releasing resumable runtimes so foreground idleness does not discard tracked background work. Preserve the saved conversation and serialize prompt admission with runtime closure; allow hosts to disable collection.
* docs: translate idle runtime cleanup configuration and provider contract
* feat(server): collect runtimes after one idle hour with optional provider vetoes
Keep callers resident while local or remote finish notification intent remains outstanding. Daemon-owned work determines baseline eligibility; provider checks add optional vetoes. Own the idle clock and sweep lifecycle in one cleanup module while the manager retains guarded closure.
* feat(agents): control idle runtime release live from host settings
Let hosts retain runtimes without restarting the daemon. Disabling invalidates pending collection decisions while preserving idle clocks for re-enabling. ACP-owned terminals and pending adapter work veto collection until they finish.
* fix(settings): clarify idle agent release with an info tooltip
