* fix(#4458): reuse detectSubRepos for new-project.md's sub-repo detection

new-project.md's Step 5.1 (Sub-Repo Detection) ran its own bash predicate:

  find . -maxdepth 1 -type d -not -name ".*" -not -name "node_modules" \
    -exec test -d "{}/.git" \; -print

`test -d` requires .git to be a DIRECTORY. A linked git worktree's .git is
a FILE (a `gitdir: <path>` pointer), so this predicate silently excluded
valid linked-worktree children while still finding ordinary clones.

src/core-utils.cts's detectSubRepos(cwd) already handles this correctly
(fs.existsSync, type-agnostic) but had zero callers anywhere in the
codebase -- orphaned logic the workflow never actually used, despite
duplicating a narrower version of the same check inline.

Wired detectSubRepos into cmdInitNewProject's JSON output as a new
sub_repos_detected field (matching the file's existing pattern of
similar directory-scan-derived fields like has_existing_code/
is_brownfield/has_codebase_map) and replaced the workflow's raw find
fence with a gsd_run query init.new-project call reading that field --
removing the duplicate, narrower detection logic entirely rather than
patching it in place, per the issue's own "reuse a central policy"
framing.

Added the missing .git-as-FILE test case to the existing
tests/core-utils.test.cjs detectSubRepos coverage (proving the helper
was already correct -- the defect was entirely in the unwired workflow
predicate) plus CLI-level end-to-end coverage in
tests/init-manager.test.cjs using a REAL `git worktree add` fixture,
matching the issue's own reproduction steps, alongside an ordinary
child-clone case and a non-repository-directory negative case.

Refreshed tests/fixtures/compact-content-benchmark-baseline.json (gsd-test
caught the drift from new-project.md's byte-count change; the benchmark
script itself always exits 0 -- report, not gate -- but the wrapper test
enforces the committed baseline stays in sync).

Emitted-Drift-Ack-Growth: new-project.md — #4458 replaces the raw find predicate in Step 5.1 with a gsd_run query call reading the new sub_repos_detected field, net +140 bytes

* fix(#4458): bound the new git worktree add spawn with a named timeout

CI's lint-tests caught two ESLint findings my local gsd-test run
couldn't see (gsd-test's matrix doesn't run npm run lint:ci -- same gap
already observed on #4456's PR):

- local/no-unbounded-spawn: the new execFileSync('git', ['worktree',
  'add', ...]) call had no timeout, an indefinite-hang risk.
- local/no-adhoc-timeout-literal: my first fix (a bare `timeout: 15_000`
  literal) was itself flagged -- two independent hardcoded copies of a
  guessed timeout can silently drift or collide (this repo hit exactly
  that on 2026-09-06, PR #4428).

Fixed by importing GIT_FIXTURE_TIMEOUT_MS from tests/helpers/timeouts.cjs
-- `git worktree add` checks out files into a new working tree, the same
"construction" weight class as init/config/add/commit that constant
already covers, not plain plumbing (GIT_TIMEOUT_MS's class).

Verified via `npm run lint` directly (clean) before re-running gsd-test.

* fix(#4458): reduce redundant git subprocess overhead in new tests

CI's full-test Windows shard 2/3 failed: chunk 1/9 (306 files) exceeded
its internal 600s budget and was force-killed, with an unrelated file
(codex-config.test.cjs) in flight at the moment of the kill -- meaning
the chunk's AGGREGATE runtime, not any single hang, blew the budget.

This PR's own three new tests each independently called
createTempGitProject() (git init + a commit), and one of them also runs
git worktree add -- real subprocess spawns, each Defender-scanned on
Windows CI (tests/helpers/timeouts.cjs's own documented rationale for
why Windows spawn classes get generous budgets). That's a genuine,
quantifiable overhead addition to the exact chunk that timed out, not
something to wave off as unrelated flake without checking.

Two of the three tests never actually needed a real git repo --
detectSubRepos only inspects a CHILD directory's own .git, never the
root's git state, and the existing SUBCOMMANDS loop earlier in this same
file already proves `init new-project` succeeds against a plain,
non-git createTempProject() fixture. Switched those two tests to the
lighter fixture, leaving only the one test that genuinely needs a real
repo (git worktree add requires one) on createTempGitProject().

Fixed 4548

/gsd-new-project's sub-repo detection now finds linked git worktrees — a linked worktree's .git is a file rather than a directory, and the previous detection predicate silently excluded it from the multi-repo prompt.
