garrytan 337d34fe16 E4: fingerprint under a read-only .git via a private object dir owned by review-log
Codex's sandbox mounts .git read-only, so gstack-wtree's git add -A could not
write blobs and /review lost its start capture. gstack-review-log now creates
a private 0700 object directory under TMPDIR, passes it to gstack-wtree (which
writes new objects there with the common-dir object store, resolved before
exporting, as an alternate, so linked worktrees work), exposes it to the
bindReview/checkSharedLibsReuse consumers that read the tree and blobs, and
removes it on EXIT/INT/TERM after they finish. gstack-wtree prints one stderr
line and exits 1 on a failed write or unwritable TMPDIR instead of printing a
partial hash; review-log no longer swallows that line. Standalone gstack-wtree
keeps writing to the repository store so git diff between saved snapshots
(/ship) still works.

# gstack-review-log — atomically log a review result
# Usage: gstack-review-log '{"skill":"...","timestamp":"...","status":"..."}'
#
# Before reading a diff: gstack-review-log --start review
# After that pass: gstack-review-log '{...,"completed":true,"converged":true}' --finish TOKEN
# Diff reviews get wtree only from a consumed, matching start capture on an
# unchanged tree. Completion/convergence are reviewer-reported, not proof that
# a model read the code. Caller-supplied binding fields are always discarded.
# Plan-tier rows retain their legacy binding behavior.
