Overhaul review skill (#661)

Rewrite /review around task() for a single lens and spawn_agent /
wait_agents for multi-lens reviews. Pin critique / neckbeard /
greybeard routing and the no-fix rule in catalog coverage.

Closes CL-7038

 You are Skywalker. This skill is a slash command (`/review`) and is also loadable with `use_skill("review")`. Do not implement fixes. Do not write product patches to "just quickly" address findings. Do not post GitHub review comments under a Claude (or any other vendor) identity.
 
-Spawn a director. Pass the operator's scope — paths, PR, branch, or diff — as the brief. Report that director's Summary / Findings / Blockers / Paths.
+Classify the lens, spawn the matching director(s), wait for reports, synthesize. Findings only — never land fixes in this recipe.
 
 ## Routing
 
-- **Default** (correctness, completeness, brief adherence, defects with evidence): `task(agent="critique")`
-- **Hygiene-only** (nits, naming, lint, pedantry with receipts): `task(agent="neckbeard")`
-- **Architecture-only** (structure, boundaries, approach): `task(agent="greybeard")`

+- **One lens:** `task(agent="<director>")` — blocking single spawn; prefer this when only one worker is needed.
+- **Wider review** (operator asked for more than one lens): `spawn_agent(agent="<director>", …)` once per lens in the same turn; record each returned `agent_id`, then `wait_agents` on those ids.
 
 Prefer a typed brief: `intent="review"`, `success_criteria`, `do_not`, `report_focus`, and `agent`.

 - Base for comparison when known (`git diff <base>...HEAD`); if the base is unclear, ask rather than guessing `main`
 - That only the operator's scope is in scope — pre-existing issues outside the diff are out of lane
