Add randomized exponential backoff to file lock retries

[jancurn]

Summary

Improved file lock retry mechanism by enabling randomized exponential backoff to reduce contention when multiple processes compete for the same lock.

Changes

• Enabled the randomize option in the retry configuration for withFileLock() function
• This causes retry delays to be randomized within the exponential backoff range, preventing thundering herd scenarios where multiple processes retry simultaneously

Implementation Details

The change modifies the retry strategy in src/lib/file-lock.ts by setting randomize: true in the retry options. Combined with the existing minTimeout: 100 and maxTimeout: LOCK_TIMEOUT settings, this ensures that when multiple processes are waiting for a lock, their retry attempts are staggered randomly rather than synchronized, significantly reducing lock contention and improving overall system performance.
