fix(actions): avoid inactive PR runs

[seonghobae]

Summary

• stop CI from creating no-op workflow runs when a pull request returns to draft or closes
• retain exact-head evidence for opened, synchronize, reopened, and ready-for-review events
• remove unreachable closed-action checks from all four CI admission guards
• preserve test(ci): define fail-closed docs-only partition contract #282 as the prerequisite without modifying its branch

Stack

• base: test(ci): define fail-closed docs-only partition contract #282 (fix/docs-only-ci-partition)
• this PR contains only the trigger-admission delta

Verification

• python3 -m unittest tests.test_repository_contract (12 passed)
• actionlint .github/workflows/ci.yml
• git diff --check
