fix: pre-landing review fixes (27 specialist findings, 3 critical)

Specialist army findings, all quote-verified before fixing:

Security: careful force-push guard now catches git's plus-refspec force
syntax (git push origin +main carried force with no flag — silently allowed
before) and refspec-form targets (HEAD:main); default-branch matching is
tokenized FIXED-STRING comparison on the full branch path (slashed defaults
like release/2.0 work; no ERE interpolation), glob-safe via noglob. HIGH rm
tier is tokenized too: trailing long options (--no-preserve-root) and /* are
root-class. Stored evidence fingerprints are 40-hex re-validated before
reaching git argv. normalizeForDetection sweeps ALL Unicode format chars
(\p{Cf}: soft hyphens, bidi marks, tag chars) instead of five enumerated
zero-widths. The wiring scanner gains flagless gh pr/issue view patterns. The
release-body banner tripwire diffs against the fetched original so a hostile
pre-existing banner string can't permanently DoS doc updates. Ship/land
evidence checks now pass --expect-cmd (a green `echo ok` recorded under the
label can never mint FRESH); package.json stays allow-listed with the
residual documented.

Performance: gstack-wtree seeds its temp index by COPYING the real index
(stat cache preserved — measured 40x faster than read-tree seeding, identical
hash) with read-tree fallback; evidence uses findLast and one gstack-slug
spawn; the stream pump honors backpressure via drain; careful's pattern block
short-circuits before slug resolution when no pattern file exists.

Testing: the gh-failure envelope test was VACUOUS (killing PATH killed the
bun shebang before the code under test ran) — replaced with a PATH gh shim
that exercises the real branch, plus shimmed happy paths (issue/pr-body/
unparseable JSON); evidence check --all + empty ledger + non-numeric
--max-age (now a usage error, was silent fail-open) covered; HIGH-tier
variants pinned; hook analytics respect GSTACK_HOME so tests stop writing the
operator's real skill-usage.jsonl.

Maintainability: dead exit ternary removed; flagValue deduped into
bin-context; sentinel defusal derived from the banner constants (no invisible
literals — \u escapes only); scratch-repo git fixture extracted to
test/helpers/scratch-repo.ts (one hermetic incantation, three consumers);
shared gstack_hook_log_fire in hook-extract.sh; the dashboard/land diff-scoped
row lists are aligned (codex-review) and drift-pinned.

**Staleness detection:** After displaying the dashboard, check if any existing reviews may be stale:
- **Content-first rule (diff-scoped rows only: \`review\`, \`adversarial-review\`, ship-stage entries).** Parse the \`---WTREE---\` and \`---DIRTY---\` sections from the bash output. If an entry has a \`wtree\` field AND it equals the current \`---WTREE---\` value AND the entry's \`dirty\` is false AND \`---DIRTY---\` is false, the review is CURRENT — identical content, regardless of commit count, rebase, or amend. Skip the commit-count heuristic for that entry and show no staleness note.

- Plan-tier rows (plan-ceo-review, plan-eng-review, plan-design-review) grade a plan file, not the repo tree — never apply the wtree rule to them; they keep the 7-day freshness logic. If such an entry carries a \`plan_sha256\` field, you MAY compare it against the current plan file's sha256 and note "plan changed since review" on mismatch.
- Fallback (no \`wtree\` on the entry, wtree mismatch, or either side dirty): parse the \`---HEAD---\` section to get the current HEAD commit hash. For each review entry that has a \`commit\` field: compare it against the current HEAD. If different, count elapsed commits: \`git rev-list --count STORED_COMMIT..HEAD\`. If that command FAILS (the stored commit was rebased away), grade UNKNOWN and treat as stale — do not error. Display: "Note: {skill} review from {date} may be stale — {N} commits since review"
- For entries without a \`commit\` field (legacy entries): display "Note: {skill} review from {date} has no commit tracking — consider re-running for accurate staleness detection"
