feat(review): confidence calibration framework + short ID fix (v0.1.42)

Evidence validation on phase done now requires per-question scores:
- plan_review: --score N --evidence "Q1:3 Q2:2 Q3:3 ..." (all 10 questions)
- impl_review: --score N --evidence "Q1:3 Q2:2 Q3:3 ..." (all 10 questions)

If fewer than 10 question scores provided, flowctl REJECTS the phase done.
This prevents the fn-8 audit finding where --score 24 was provided without
actually running the forcing questions.

Validation: count Q-score entries, reject if < expected, print evidence total.
SKILL.md updated with full evidence format in phase done commands.
370 tests pass.
