hotfix.yml was deleted (folded into release.yml). Remove the now-broken
release-coverage-scope and policy-release-no-npm-self-upgrade assertions that
readFileSync'd hotfix.yml (release.yml equivalents retained), drop the dead
install-smoke.yml path trigger, and update VERSIONING.md / docs/branching.md
prose to describe hotfixes via the Release workflow with a patch version.

release.yml (rc + finalize) and hotfix.yml (finalize) ran the full
`npm run test:coverage` suite on the release path, redundantly re-running
the integration/install/security/slow suites that already passed on the
PR lanes into next. Switch those three sites to `npm run test:coverage:unit`
(same c8 config, unit suite only) to cut release latency. Full-suite
coverage remains available via the dedicated lanes / `test:coverage:all`.
Adds a workflow-contract regression test asserting the release/hotfix gates
invoke the unit coverage command (exact-line match, not substring).
