Dropping archive-inputs from the result jobs replaced the whole `needs`
list with the job's own name: `build-win32` needed `build-win32`, and
`build-darwin` needed `build-darwin`. GitHub rejects a workflow with a
cyclic job dependency outright, so the dispatch died at parse time — and
the result jobs read `needs.build-win32-release.result` /
`needs.build-win32-commit.result` (the darwin pair likewise), which are
only reachable through a declared `needs` entry.
Name the trust-branch legs instead, and pin the contract: no job may
need itself, and every `needs.<job>` read in an `if:` or expression must
be a declared dependency.
