Worktree 0.14.0

• worktree prune-archives removes archives a remote fully holds. A dry-run, the default, lists
  each archive directory with its bytes and verdict, then the bytes removable and refused.
  --apply --id <directory> deletes an archive only when HEAD and every unique commit it records
  are ancestors of a ref a configured remote freshly advertises, it holds no dirty.patch and no
  nested repository image, its tree is gone, and its directory holds only the files its manifest
  names. Every other archive is refused with its reason (CommitsNotOnRemote, UncommittedState,
  NestedRepositories, TreeStillPresent, RemoteProofUnavailable, UnrecordedContent,
  InvalidManifest) and kept; no flag forces a removal. Selection follows gc: --repo,
  --scope repo|profile, --id.
• An archive manifest that names a bundle or patch file other than commits.bundle and
  dirty.patch is refused as archive-invalid; no release writes another name.
• The GitHub Release body is the version's section of this changelog, not the tag message.
