docs: annotate dated artifacts referencing lifted bash tests

- RELEASE-NOTES.md: note that test-requesting-code-review.sh and
  test-document-review-system.sh were lifted into drill scenarios
  on 2026-05-06; references are preserved as dated artifacts.
- docs/superpowers/plans/2026-03-23-codex-app-compatibility.md:
  note that tests/skill-triggering/ was lifted into drill scenarios
  on 2026-05-06; the run-all.sh reference is a dated artifact.

Subagent second-pass scrub confirmed no other active references in
the tree (excluding evals/ and the spec/plan for this work itself).

 - **Single source of truth** — the persona/checklist that previously lived in both `agents/code-reviewer.md` and the skill's placeholder template (and drifted independently) is now one file.
 - **`subagent-driven-development` follows suit** — its `code-quality-reviewer-prompt.md` now dispatches `Task (general-purpose)` instead of the named agent.
 - **Behavioral test added** — `tests/claude-code/test-requesting-code-review.sh` plants real bugs (SQL injection, plaintext password handling, credential logging) into a tiny project and asserts the dispatched reviewer flags every planted issue at Critical/Important severity and refuses to approve the diff.

See `evals/scenarios/code-review-catches-planted-bugs.yaml` and `evals/scenarios/spec-reviewer-catches-planted-flaws.yaml`. The references above and below are preserved as dated artifacts of the work this section describes.
 - **Codex and Copilot workaround docs trimmed** — the "Named agent dispatch" sections in `references/codex-tools.md` and `references/copilot-tools.md` documented how to flatten a named agent into a generic dispatch. With no named agents shipping, the workaround is unnecessary; both sections were dropped.
