Jira issue: CRDB-65222

Start with external/com_github_cockroachdb_pebble/wal/standalone_manager.go:157-161 and follow ReuseForWrite through pkg/storage/fs/fs.go:442 and the Pebble VFS paths in the stack trace. Trace how WAL rotation reaches filenames.go:302 and determine why the rename reports a missing file. Done means the reported crash is explained and a validated fix prevents this failure path.
