document-release: changelog sell test as three questions, not a 0-3 score (s10 M6)

The threshold stays (fewer than two answered = needs attention, not
replacement). M4/M5 (NEVER CLOBBER / NEVER BUMP) keep their wording; the
integrator owns the eval-gated rewrite.

W7a pin: workflow-excerpt:170 'Entries scoring <2 need attention, not
replacement' becomes a case-insensitive check that weak entries get
attention, not replacement.

Template-only commit: generated SKILL.md is expected red until the regeneration commit.
