IronStorage code continues to own clone staging, checkout, merge, conflict, and
rollback behavior.
SSH push opens the same verified and authenticated session-channel boundary for
`git-receive-pack '<path>'`. Storage validates the advertisement, rejects
non-fast-forward updates before sending, constructs the complete reachable
object pack, then half-closes channel input and drains the status and bounded
stderr streams. The remote-tracking ref advances only after `unpack ok`, an
`ok` for the selected ref, a zero service exit, and clean channel completion.
Unpack and ref-policy rejections remain typed failures; a malformed response,
disconnect, or cancellation after sending is an unknown outcome that requires
a fresh fetch before retrying and is never replayed automatically. Synchronize
always completes pull first and cannot open receive-pack after a failed,
cancelled, or conflicted pull.
Pull refuses a dirty worktree. It fast-forwards when possible and otherwise
uses the embedded three-way tree merge. Unresolved paths are returned as typed
`MergeConflicts`; no conflict markers or partial checkout are written. Checkout
