Merge origin/main (v1.91.7.0) into test-audit-reduction

Keep both intents: v1.91.7.0's functional QA, docsync and exploratory
paid cases and their free owners stay; this branch's deletions stay
deleted. main's new paid keys follow the derived-closure touchfile rule
(free *.test.ts paths dropped, static helper/fixture closure added), its
new helper-only tests join the ratchet baseline, and its free selection
examples that named free test files now assert the derived selection.

Periodic CI keeps seven slices without the retired Autoplan slice; the
gate census keeps seven single-worker slices with --skip-judges. Wall
and census literals are recomputed from the merged planner, durations
are re-recorded on Ubicloud, and VERSION stays 1.91.8.0 above 1.91.7.0.
