evals: kill the 3,372-line zombie monolith; revive 4 never-run tests

test/skill-e2e.test.ts survived the v1.56 split as a zombie: the paid
glob needs the skill-e2e-* hyphen, so with EVALS=1 NOTHING has executed
it for ~8 releases — and it held the ONLY implementations of four
map-registered tests: review-coverage-audit (gate), plan-eng-coverage-
audit (gate), ship-triage (gate), ship-idempotency (periodic). Three
gate tests silently never ran — the exact 0%-execution class this
branch exists to kill.

Rehomed into test/skill-e2e-coverage-audit.test.ts, -triage.test.ts, and
-ship-idempotency-sdk.test.ts with bodies byte-identical modulo collector
wiring and fixture extraction (drift observed in the skills since v1.56
is DOCUMENTED in each header, not fixed — their first paid run in 8
releases must attribute failures to drift, not to this move). All 24
other monolith names were true duplicates of the split files — dropped
with the monolith. Matrix rows added to both eval workflows; the paid
glob's zombie-exclusion is now a commented regression pin.
