fix(client): make the disaster-recovery path actually work

Review found the read path scoped to the CURRENT device's uuid, which breaks
the exact case snapshot mode exists for: when the laptop dies, the
replacement machine has a new id, so snapshots printed 'no restore points
yet' while the backups sat on the forge, and restore errored. Reproduced,
then fixed by unscoping the READ only. Writing stays device-scoped (two
machines must not overwrite each other) and pruning stays device-scoped
(machine A must not apply its clock to machine B's refs); the docstring now
says why the three differ.

Also from the same review:
- mirror mode printed a %cI timestamp that restore could not accept, so
  copying the first column looped the user back to snapshots. It now matches
  the log, and refuses an ambiguous timestamp (two commits in one second)
  with the candidate ids instead of guessing.
- the size guard advised 'add a .gitignore' while measuring with a plain
  walk that ignored one. It now measures what git would sync, through a
  throwaway git dir outside the folder so a refused add leaves no .git
  behind.
- get --all caught only SystemExit, so a RuntimeError from any git call
  abandoned the remaining repos.
- get --all mapped alice/notes and bob/notes to one path and reported the
  second as 'already present'. Clashes now clone to <owner>-<name> and say so.
- the prune clock was in-memory, so watch --once under launchd pruned every
  run. Persisted in config.

153 tests. Live-verified on the beta forge: machine A backed up uncommitted
work and was deleted; machine B, different device id, cloned the repo, listed
A's snapshot and restored both files.
