Pure move, behaviour-identical. The ZIP swap journal, owner lock and
journal-driven recovery (~250 lines) are unrelated to the git-marker
restore, yet had grown _early_recovery.py from 684 to 1455 lines. They now
live in the topical sibling hermes_cli/_early_recovery_zip.py.
restore_interrupted_pull imports it only when the journal exists, so the
git-marker repair and its published closure (RECOVERY_CLOSURE) still need
only _early_recovery.py; ZIP_SWAP_JOURNAL stays there for that fast-path
stat. write_durable_text stays too (the marker and fleet writers use it).
Importers and the one monkeypatch seam (_lock_fd, read by the lock) now
point at the module that reads them. (review K132361 shape gate)
