Addresses Copilot review round 4 on #2239. Both findings are regressions
I introduced in round 3 and both are correct.
Round 3 moved the lookup from `releases/latest` to the release LIST, to
rank by version rather than by GitHub's designated latest — but kept the
404 suppression that only made sense for the old endpoint. The list
endpoint answers "this action cuts no releases" with a successful empty
array, so a 404 there does not mean that at all: it means the repository
is missing or inaccessible, i.e. a `uses:` ref the sweep cannot check.
Converting it to null silently dropped a broken or renamed action from
the flow that replaced Dependabot — the same silent-success shape this
PR has been closing everywhere else, reintroduced one layer down.
Every non-zero status is now fatal and `isMissingRelease` is gone
entirely; the benign no-releases case is the successful empty array,
covered by its own test.
`buildClearedBody` also overstated its all-clear. Refs pinned to a commit
SHA or a branch return null from `parseVersionRef` and are never ranked,
so "no workflow `uses:` ref is behind" asserted a check that had not
happened for them. It now says version-pinned refs and names the
exclusion explicitly.
Both guards are mutation-checked: restoring the 404 suppression, and
dropping the SHA/branch qualification, each fail exactly one test.
