jif d28be12577 Honor per-thread unload delays in app-server (#55270) ...

## Why

Thread unload timing used the server-wide delay, ignoring per-thread configuration overrides. Clients need to control how long individual idle, unsubscribed threads remain loaded.

## What changed

- Resolve unload timing from each loaded thread's `thread_unload_delay_secs` configuration. Setting it to `0` allows immediate unloading once the thread has no subscribers or activity.
- Allow this runtime retention override in `experimentalPredictionMode` forks while continuing to reject other configuration overrides. Reject negative values and delays too large to schedule.
- Replace the source-specific immediate-unload behavior with explicit configuration.

## Testing

Extend integration coverage for per-thread delays, unloading after active turns finish, fork overrides, and invalid prediction-fork delays. Verify that immediate unloading preserves persistent history and that cold resumes and ordinary nested forks use their default delay instead of retaining the previous runtime's override.
