Failed to persist fork: {persistence_error}; cleanup also fa

Error message

Failed to persist fork: {persistence_error}; cleanup also failed: {}

What it means

fork cleanup path: the forked thread was built in memory but persisting it to the store failed, and rolling back the already-saved turns/items also failed (both errors are reported). The system is left possibly partially persisted, so the message carries both the persistence error and the cleanup error for diagnosis rather than hiding one.

Solutions

1. Check both embedded errors (store persistence and cleanup)
2. Inspect the thread store for partially-saved fork artifacts
3. Free disk/lock contention and retry the fork
