feat(skills): claimed limitations now require evidence, everywhere + wave follow-ups filed

Every tier-2+ skill's preamble gains one directive distilled from nine live
release failures in two days on the fork: a claimed limitation or
requirement ('the API can't do this', 'X requires a credential',
'impossible on this platform') is a material claim, stated only with the
verbatim error, the documented statement, or a live probe in hand —
pattern-matching a failure to a familiar story is not evidence, and a cheap
probe runs BEFORE asking the user or declaring a step blocked. ONE directive
adapted into the preamble resolver; the fork's full judgment contract is
deliberately not imported. Full regen (46 files), ship goldens refreshed,
parity guards bumped with the measured ~0.45KB/skill (investigate, autoplan,
plan-design-review, office-hours), Step 0.9 registered as an intentional
sub-step.

Approved deferrals filed: persona-fleet hostile-user harness + answer-key
methodology in TODOS; the fork's question-budget ACCOUNTING judgment (never
its 5/8/12 constants) folded into the V1.1 pacing design doc; the Apple
adapter added to #1882's coverage note.

Ported from time-attack/gstack (GStack 2).
