feat(missions): wire copy-in/copy-out behind CLAWMATES_MISSION_FS=copy

With the flag set, ensure_container omits the /mission bind, the checkout
is pushed into the container at phase launch, and the agent's work is
pulled back before capture.

The simplification that makes this small: sync_out unpacks over the SAME
host path the checkout came from. The host directory stays a server-owned
staging area with exactly one writer, and capture_phase_diff_at needs no
change at all — it still finds a normal checkout exactly where it always
has. Delivery, gating, commit and push are untouched.

Two failures are deliberately loud rather than silent:

- copy-IN failure fails the phase launch. Continuing would start a phase
  against an empty directory, and the agent would cheerfully report having
  done work on a repo that was not there.
- copy-OUT failure SKIPS capture. Capturing anyway would diff a stale host
  tree and record "no changes" for work that exists — success reported for
  nothing, which is the exact failure mode this codebase keeps paying for.

Opt-in: the bind path is what production has run since the beginning, and
the test asserts a near-miss value leaves it there rather than silently
switching every mission.

414 tests, clippy clean.

+//! One run of the library: find, skip what we have, shelve the rest.
+//!
+//! This is the piece that makes the others a *job* rather than parts on a
+//! bench. Order matters and it is deliberate:
+//!
+//! 1. **search** arXiv for candidates
+//! 2. **skip** everything already on the checkmark list — before any download
+//! 3. **fetch** the PDF for what is left, and verify it really is a PDF
+//! 4. **shelve** it in the blob store
+//! 5. **catalogue** it: write the vault note
+//! 6. **check it off** so next week skips it
+//!
+//! Step 2 comes before step 3 on purpose. Checking after downloading would
+//! still dedupe the catalogue, but it would re-download every paper we already
+//! have, every week, forever — and the whole point of the checkmark list is to
+//! not do the work twice.
+//!
+//! # Nothing new is a success, not a failure
+//!
+//! A weekly run that finds no new papers has worked correctly. A run that
+//! *crashed* has not. [`Harvest`] keeps those apart, because collapsing them
+//! is precisely the "reported success while doing nothing" shape that this
+//! codebase has been bitten by repeatedly. `shelved == 0` with `failed.empty()`
+//! is a quiet week; `shelved == 0` with failures is a broken run.

+//! Move a mission's checkout in and out of its container, instead of sharing it.
+//!
+//! Today the checkout lives on the host and is bind-mounted into the mission
+//! container. That single directory is written by **two users** — cm-api as
+//! uid 65532 and the agent as root — and every bug that pattern can produce,
+//! it has produced:
+//!
+//! | Symptom | Fix that was needed |
+//! |---|---|
+//! | `.git/objects` permission denied | `core.sharedRepository=0777` |
+//! | capture base overwritten each phase | advance the base after commit |
+//! | `.git/COMMIT_EDITMSG` root-owned | unlink before commit |
+//! | `reset --hard` deleting a prior phase | `.git/clawmates-in-use` marker |
+//!
+//! Four fixes, one cause. `core.sharedRepository` was never a general
+//! solution — it covers objects and refs, and every *other* file git touches
+//! is a fresh opportunity.
+//!
+//! Copy-in/copy-out removes the cause: the agent owns its filesystem
+//! completely, as root, with no other writer. Nothing on the host is shared,
+//! so nothing on the host can collide.
+//!
+//! # Cost
+//!
+//! Measured on gw-04 against a real 65 MB checkout of this repository:
+//! **0.23s in, 0.18s out**. That was the one open risk in the plan — a
+//! monorepo copied per phase — and it is not a risk at this size. Measure
+//! again before assuming it holds for a repository an order of magnitude
+//! larger.
+//!
+//! No compression: the payload crosses a local Docker socket, so gzip would

+//! Finding papers, shelving them, and cataloguing them.
+//!
+//! The library has three parts and it matters which is which:
+//!
+//! - **arXiv** is where papers are *found*.
+//! - **The blob store** is the *shelf* — the PDF itself lives there.
+//! - **The vault** is the *card catalogue* — a markdown note per paper, with
+//!   the metadata and a pointer to the shelf.
+//!
+//! Plus [`crate::corpus`], which is the list of checkmarks: it is what stops
+//! the same paper being fetched twice across weekly runs. That list is the
+//! reason this can be a *continuous* job rather than one that redoes itself
+//! forever — the failure that killed the previous attempt at this (migrations
+//! 0030-0044, dropped in 0053).
+//!
+//! # The contract that ties it together
+//!
+//! Every note this module writes carries `source_id: arxiv:NNNN.NNNNN` in its
+//! frontmatter. `corpus::parse_note` reads exactly that key, so re-indexing
+//! the vault re-derives the checkmark list from the notes themselves. The
+//! catalogue is authoritative; the index is rebuildable from it. If the
+//! database were lost, a re-index of the vault would restore what we have.

+//! Which phase-config keys the platform actually reads.

+//! it, so a key could be accepted, validated, stored, rendered — and consumed
+//! by nobody.
+//!
+//! `task` was exactly that. Every phase of every mission received identical
+//! instructions because the runner selected only the mission description; the

+//! it: two coding phases with different `task` values produced the same two
+//! files. There was no error, because there is nothing to fail — an unread key
+//! is indistinguishable from a key whose value happens not to matter.
+//!
+//! This module is the missing link. Every key here names the code that reads
+//! it, `unknown_keys` reports anything else, and a test asserts the shipped
+//! recipes only write keys that exist. It cannot make a reader appear, but it

+# Stream an image between two remote hosts. The tar crosses two SSH
+# connections spliced through this workstation, so a stall on either side
+# truncates it — that surfaces as `unexpected EOF` from `docker load`, which
+# is a genuine failure and was previously indistinguishable from success
+# because nothing checked afterwards. Compress (these images are mostly
+# filesystem, and less bytes is less exposure to a stall) and set pipefail so
+# a failed `save` cannot be masked by a `load` that exits 0 on a short stream.

 # Load only if the target lacks the exact image (skips re-transferring unchanged
 # multi-hundred-MB agent images to every node on each code deploy).
+#
+# Verifies by image ID afterwards rather than trusting the exit status: a
+# truncated stream can still leave a partially-populated image, and shipping a
+# corrupt agent image to every fleet node is worse than failing the deploy.
+# One retry, because the observed failure is a transient stream stall.
+#
+# Identity is the image's `Created` stamp, NOT its `Id`. A BuildKit image on
+# the build host carries attestation manifests that `docker save | docker load`
+# does not reproduce, so the same build legitimately arrives with a different
+# Id and a different reported Size — comparing Ids fails every transfer of a
+# correctly-shipped image. `Created` comes from the config blob, survives the
+# round trip, and is what actually answers "is the new build here".
