fix(#666): pr-branch silently ignored planning.sub_repos (#667)

* fix(pr-branch): handle sub_repos from config with git -C (#666)

Adds a `handle_sub_repos` step between `detect_state` and
`analyze_commits`. When `planning.sub_repos` is set in config, the
workflow now:

- Reads sub-repo paths via `gsd_run query config-get sub_repos`
- Skips the step entirely when the list is empty/null/[]
- Scans each repo with `git -C "$REPO" status --porcelain`
- Offers the user all/select/skip choices
- For selected repos: creates a PR branch, commits all staged/unstaged
  changes, pushes, and opens a companion PR via `gh pr create`

All git commands use `git -C "$REPO"` — never `cd "$REPO"` — because
shell state does not persist between agent-executed commands.

Closes #666

* chore: update changeset pr number to 667

* fix(pr-branch): address maintainer review — correct seam, behavioral tests, robustness

Resolves all three blockers and seven robustness issues raised in PR #667 review:

Blockers:
- Use `planning.sub_repos` (not top-level `sub_repos`) so config-get actually resolves
- Replace prose grep test with behavioral fixture tests using runGsdTools + local bare repo
- Extract sub-repo git work into new `cmdPrSubrepo` seam in src/commands.cts;
  never uses git add -A — stages explicit files only (universal-anti-patterns.md:44)

Robustness:
- Dirty-repo list persisted via mktemp/cat, not bash arrays (cross-block safe)
- Branch name embeds repo slug (${CURRENT_BRANCH}-${REPO_SAFE}-pr) to avoid collision
- push --set-upstream so gh pr create finds the branch
- Sub-repo base branch resolved via ls-remote with fallback to repo's default branch
- Remote slug parsed with /github\.com[:/]/ (handles SSH + HTTPS + .git-less URLs)
- rollback() cleans up branch on any mid-sequence failure
- node -e replaces jq (always available, no undeclared hard dep)

* fix(pr-branch): security guard, push timeout, rollback fix, porcelain fix

Security (Blocker 1):
- Use security.cjs validatePath() in cmdPrSubrepo for symlink-safe workspace
  containment check — rejects ../escape, absolute paths, and symlink traversal
- Add negative regression test: '../escape' repo path must be rejected

Robustness:
- Push uses timeout: 60_000 ms (network op needs more than the 10 s default)
- Capture prevBranchName before checkout -b so rollback uses explicit name
  instead of git checkout - (fails on fresh single-branch repos)
- Porcelain path parse: line.trimStart().slice(2).trim() handles all XY
  combinations and the execGit global-trim edge case uniformly

Tests: 17/17 pass, lint: 0 errors

* fix(pr-branch): move regression tests to commands.test.cjs, add core.quotePath=false

- Move cmdPrSubrepo behavioral + workflow source-invariant tests from
  standalone bug-666-*.test.cjs into tests/commands.test.cjs under
  describe('pr-subrepo') per TESTING-SUITES.md policy (no new bug-* files).
  Adds allow-test-rule: source-text-is-the-product see #666 for the
  workflow-source-invariant suite.
- Add -c core.quotePath=false to git status --porcelain call so non-ASCII
  filenames (e.g. café) are not C-escaped, keeping slice(2) parse correct.

* fix(pr-branch): remove obsolete regression tests for sub-repos handling

* fix(pr-branch): update workflow-size-baseline, add dirty-scan timeout

- Regenerate tests/workflow-size-baseline.json for pr-branch.md growth
  (+handle_sub_repos step, +timeout addition).
- Add { timeout: 10_000 } to the execFileSync git status --porcelain
  call in the handle_sub_repos dirty-scan (repo convention: every git
  subprocess is bounded, never hangs).

* chore: regenerate INVENTORY-MANIFEST after rebase onto next

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(#666): handle rename staging and split changedFiles from filesToStage

For git mv renames, the old path no longer exists in the worktree after
the move — staging it with git add fails. Split parsing into changedFiles
(both paths, for result.files) and filesToStage (new path only for
renames; old is already staged by git mv). Also adds porcelain tests
for staged renames, non-ASCII filenames, and a fast-check property test.

* fix(#666): rollback on push failure in cmdPrSubrepo

If push fails the branch only exists locally; rollback cleans it up so
the sub-repo is not left in a half-committed state.

* fix(#666): do not rollback after commit on push failure; add push-fail regression test

Post-commit push failures are network/auth/policy issues — the user's work
is already committed on the local branch. Calling rollback() at that point
force-deletes the only ref holding the commit (data loss). Leave the branch
in place and emit a retry instruction instead.

Adds a regression test (pre-receive hook that rejects all pushes) asserting
the branch and commit survive a push rejection so the failure path stays
covered going forward.

* chore: regenerate INVENTORY-MANIFEST after rebase onto next

Rebased onto current next (#1267 retired core.cjs). Stale tsbuildinfo and
a leftover bin/lib/core.cjs build artifact were masking the drift — wiped
both, rebuilt clean, and regenerated the manifest. gen-inventory-manifest
--check now exits 0.

* fix(#666): validate sub-repo paths before git invocation in pr-branch.md

The handle_sub_repos workflow ran git -C on raw planning.sub_repos config
values at two points before the pr-subrepo seam's validatePath guard ever
ran: the dirty-scan detection (git status) and the base-branch resolution
(git ls-remote / remote show). A traversal entry could point git outside
the workspace; an embedded newline could inject a spurious record into
the newline-joined dirty-file output and into the shell-interpolated
commit message.

Adds a containment check + character allowlist to the dirty-scan node
script (reject before any execFileSync), and a defense-in-depth shell
case guard on the same value before the second, independent git -C
invocation in the base-branch resolution block.

Adds a behavioral test that extracts and executes the actual shipped
node script from pr-branch.md (not a mirror) against a real traversal
target and an embedded-newline entry, asserting neither reaches git or
the dirty-file output.

Also updates the stale cmdPrSubrepo doc comment: push failures no longer
delete the branch (see prior commit), only stage/commit failures do.

* test(#666): make sub-repo traversal scan test genuinely fail-first

The outside repo's only change was an untracked file, which the ?? filter
excludes — so the repo looked clean even with the guard removed, making the
traversal assertion vacuous (it passed against a neutered guard). Commit the
file first, then modify it, so the outside repo has a tracked dirty change:
without the path guard it WOULD be reported dirty, so the test now fails-first.

* fix(#666): symlink-safe (realpath) sub-repo containment in pr-branch.md

Finding A from re-review: the workflow guard used path.resolve, which only
normalizes '..' textually and does not follow symlinks — so an in-tree symlink
whose name has no '..' or '/' (e.g. "evil" -> /outside) passed both the charset
filter and the resolve+startsWith check, letting git status / ls-remote /
remote show run against a directory outside the workspace. The pr-subrepo seam
already used fs.realpathSync (validatePath); this brings the workflow layer to
parity.

- dirty-scan: realpathSync the root once, and realpathSync each candidate before
  the containment check; skip on throw.
- base-branch resolution: replace the weak `case *..*|/*` guard with a realpath
  containment check that yields a validated absolute SUB_REPO_DIR, and run git -C
  against that instead of re-concatenating $ROOT/$REPO_REL.
- security test: add a symlink-escape entry and a positive control (legit in-root
  backend must still be reported). Confirmed fails-first — regressing the scan to
  path.resolve makes the symlink case leak.

Also fixes a misleading-fallback minor: the workflow now checks the seam's exit
status and skips the companion-PR step on failure, instead of printing
"branch pushed, open PR manually" after a real stage/commit/push failure.

* fix(#666): harden pr-branch sub-repo flow against round-12 edge cases

Pre-emptive hardening of the workflow changes from the symlink fix:

- continue-outside-loop: the "skip companion PR on seam failure" block used a
  bash `continue`, but the per-sub-repo iteration is prose-driven (the agent
  loops, not a literal `for`), so `continue` would warn and no-op. Reframed as
  prose-gated control flow keyed on $SUBREPO_EXIT — no bash loop assumption.
- Windows portability: the new symlink security case now degrades gracefully
  (try/catch around fs.symlinkSync; skip just the symlink assertion when symlink
  creation lacks privileges) so it doesn't hard-fail on Windows CI.

Verified: seam exits 1 on error / 0 on success (error() → process.exit(1),
propagated through the shim), so the $SUBREPO_EXIT check is meaningful; bash -n
clean on the touched blocks; commands 156/156; lint:ci green; manifest in sync.
