History pruning now scans lock-free and verifies the file hasn't changed, deferring the prune instead of erroring if it has.
Pruning of history.jsonl under retention rules now runs a lock-free scan first, verifying the file's identity (inode/birthtime) hasn't changed, and only takes the retention lock and rewrites the file if there's actually something to prune. If the file changes underneath the scan, pruning is deferred rather than erroring, logged as History retention prune deferred: history.jsonl changed under the scan.
