Checkpoint and recover Petri workspaces inside Docker and Daytona sandboxes
A Petri run on Docker or Daytona keeps its workspace inside the scope's
sandbox. Fabro's hooks now take the environment Petri hands them at
`scope_acquired`, run `git` inside the scope through it (the path Petri's
own sandbox-placed hooks take), and commit each stage on the run branch
with the same message and trailers as the host path. The commit leaves
the sandbox as a Git bundle, created against the newest ancestor the
snapshot repository already holds, split into 8 MiB parts (the plugin
transport reads one file up to 16 MiB), read out through the
environment's file transfer, fetched into the bare snapshot repository
on the host and named there under the checkpoint's ref. The repository
holds every checkpoint whatever the provider, and the platform records
name the same commits. The host path is unchanged; both sites share one
runner and the same commands.

Recovery is split: `recovery::plan` decides, over the records and the
snapshot repository alone, what every live workspace must sit on and
reconciles a lost record; `recover` applies it to host workspaces on the
server, as before, and reports a sandbox workspace's target as deferred.
The worker's hooks read the same plan at the scope's first acquisition
after a resume and bring the sandbox workspace to it before any attempt
runs there: verified or reset in a retained sandbox that still holds the
commit, else restored from a bundle of the checkpoint written into the
sandbox. Petri replaces a lease's lost sandbox on Fabro's request
(`LostSandbox::Replace`), so a removed container comes back fresh and
restored.

The checkpoint records are written for every provider now. A Docker
variant of the in-process hooks test moves a 20 MiB file through the
split transfer; the same test runs on Daytona when live credentials are
present. Three CLI scenarios run on a Docker environment: every stage's
checkpoint published from the container, a retained container whose
workspace drifted reset on restart, and a removed container replaced and
restored from the snapshot.
