refactor(workers): extract default workers timeout into named constant

Address review feedback on #5545: replace the magic literal `600000` in
`_getWorkersTimeoutMs()` with a module-level `WORKER_TIMEOUT_MINUTES`
constant and an explicit `* 60 * 1000` conversion, so the default value
reads as "10 minutes" at the call site.

No behavior change — default still resolves to 600000 ms.
