v0.23.0

Fixed

• Cleanup convergence when a delegating repository is deleted. Previously a
  vanished repoRoot made canonicalizePath throw: normal-path prune caught it
  and retained the run forever (its bytes never reclaimed, so maxBytes/maxAge
  could not converge), and — more seriously — a repo-gone pending cleanup intent
  made validateRepositoryRoot throw outside the per-record guard in
  replayInterruptedPrunes, aborting the entire crash-recovery pass on every run
  (a permanent block). Both paths now reconcile a repository-absent run without
  Git: prune reclaims the archive directly (no lease, no ref cleanup — the
  candidate and backup refs died with the repository, and no live checkout can
  integrate from a vanished repository), and recovery detects the absent
  repository before validation and completes or rolls back the archive by disk
  state, converging instead of aborting.
