Dmitriy Kovalenko ff2346f33f Bound waits for the thread writer coordination lock (#57360) ...

## Why

Contention on the writer coordination lock can block writer cleanup indefinitely, preventing idle threads from unloading.

## What changed

Retry coordination lock acquisition every 50 ms and return `io::ErrorKind::TimedOut` after 30 seconds of contention. This lets cleanup release writer ownership and idle unloading finish even while another process holds coordination.

## Testing

Extend writer lock coverage to check the timeout error. Update the idle unload regression test to verify that the thread closes while coordination remains locked and can resume with its persisted turn after the lock is released.
