Fix: quoted review headings start no block

Plan-lifecycle 0.17.0 (#98, pull request #99) lets one review comment hold several blocks, one per lens. To find a later block, the helper looked for a review heading after it had removed blockquote, list, and emphasis marks from each line. A passing block that quoted an earlier round then opened a block of its own:

### Code review round 2, delta

Code-review: pass

## Previous findings

> ### Code review round 1
> Code-review: fixes-required

The quoted verdict won, so the round read as fixes-required (or repair for a plan review). A delta reviewer that quotes old rounds could keep a review loop from passing. The failure was strict, never loose: a quoted heading could not turn a failure into a pass. Version 0.16.0 read only the first verdict line and did not have this problem.

What changed

• A later block starts only at a Markdown heading line: # after at most three spaces, not quoted and not a list item. Only the title after the # markers is read through emphasis and code marks (plugins/plan-lifecycle/skills/productivity/plan-manager/scripts/plan.mjs).
• Kinds and verdict lines are still read through emphasis, code marks, quotes, and list markers, as before.
• The contract's review-record rules state the heading rule (plan-contract.md).

Verification

• Red baselines: the quoted-heading case read fixes-required before the fix; the star-bullet case (* ### Code review round 1) still read fixes-required after the first commit, which code review round 1 found.
• node scripts/tests/plan-cli.mjs: 66 of 66 passed, with cases for a quoted heading, a - and a * list-item heading, an indented lens heading, and an emphasized heading title.
• bun run test:coverage: plan.mjs line coverage 99.68%.
• bun scripts/ci.mjs: passed for the repo-wide checks and both plugins.
• Code review: round 1 (full) returned pass with one MEDIUM finding, the star-bullet case; round 2 (delta) settled it.

After merge

• Release plan-lifecycle 0.17.1 (its own question).
