fix: round 7 of the release review of 6.3.0, for 6.3.1
Round 7 (516dffa..45aa9e1, WARN: 12 MAJOR, 0 BLOCKER) and the fence defect
found while writing its review.md. Each fix began with a test that failed on
0f400d3 (v6.3.0); suite 2208 (2206/0/2), 14 tests more.

- Tests-only (operator 2026-10-11): the plan's Files: alone decides, and the
  text says so (red-proof, trekexecute Sub-step B, step-implementer,
  HANDOVER-CONTRACTS). red-proof no longer reads the step's diff, so a change
  already in the tree when the step began no longer counts against it, and a
  plan placed outside .claude/ reads the same. The round-6 test that had the
  diff overrule the plan is rewritten to the new rule.
- The Files: reader keeps a plain file beside a backticked path
  (", Dockerfile", "the CLI entry src/cli.mjs", "and Makefile"). Measured on
  the 520 Files: fields in 182 plans: no field reads differently.
- Red proof reports a command its timeout killed as killed after the timeout,
  not "could not start"; the release check tells a timeout from output past
  its buffer and from another signal. One reading of a stop
  (criteria-runner stoppedBy) for red proof, the criteria runner and the
  release check.
- A trailing `# comment` is dropped in a backticked check too, and in a
  command passed as written, so the words screened are the words run.
- The release check reads a relative --review in --repo.
- The 15-minute timeout is defined once (criteria-runner.mjs).
- The findings check reads each cited file once per validation.
- One isMain helper (lib/util/is-main.mjs) for every CLI: the 31 copies of
  the realpath guard and the 20 modules still on the file:// guard, which
  exited 0 having done nothing under a symlink or a path with a space.
- The Bash guard writes its no-one-to-ask refusal once, on a direct condition.
- The findings check ends a ```json block only at a fence on its own line, so
  three backticks inside a JSON string no longer end it (also in 6.2.0).
- Brief-conformance notes: a test for test-lock green on exit 127 (it
  passed at once; it fails when 127 is read as could-not-run); the prose now
  names the git revision `@~1` as the one leading-@ exception.

Not changed: the example plan's steps 1-2 keep their tests-only warning
(operator decision 2026-10-09; the r5 test records it). Brief note 4 (a
Regression: whose runner is not installed goes to the fix rounds) is a
routing question for the operator.
