Audit finding: every workflow that emits a required-status-check name
on molecule-core's branch protection (apply.sh's STAGING_CHECKS +
MAIN_CHECKS) ALREADY uses the safe always-runs-with-conditional-steps
shape — Platform/Canvas/Python/Shellcheck in ci.yml, Canvas tabs E2E
in e2e-staging-canvas.yml, E2E API Smoke in e2e-api.yml, PR-built
wheel in runtime-prbuild-compat.yml, the codeql Analyze matrix, and
the always-on Secret scan + Detect changes. No production drift to
fix today.

Adds a regression-guard so the next path-filter / matrix refactor /
workflow rename can't silently re-introduce the bug shape called out
in saved memory feedback_branch_protection_check_name_parity:

  "Path filters … silently break branch protection because no job
   emits the protected sentinel status when path-filter returns false."

New tools:
  - tools/branch-protection/check_name_parity.sh — extracts every
    required check name from apply.sh's heredocs, then for each name
    classifies the owning workflow as safe (no top-level paths:) /
    safe (per-step if-gates without top-level paths:) / unsafe
    (top-level paths: without per-step if-gates) / unsafe-mix
    (top-level paths: WITH per-step if-gates — the workflow may still
    skip entirely on path exclusion, leaving the gates dormant) /
    missing (no emitter at all). Special-cases codeql.yml's matrix-
    expanded `Analyze (${{ matrix.language }})`.
  - tools/branch-protection/test_check_name_parity.sh — 6 unit tests
    covering each classification: safe, unsafe-path-filter, missing,
    safe-with-per-step-gates, unsafe-mix, matrix-expansion. Each test
    builds a synthetic apply.sh + workflow file in a tmpdir, invokes
    the script, and asserts on exit code + stderr substring. Per
    feedback_assert_exact_not_substring the assertions pin specific
    classifications, not just non-zero exit.

Wired into branch-protection-drift.yml so every PR touching
.github/workflows/** runs the parity check; the existing daily
schedule covers between-PR drift. The check is cheap (~1s) and runs
without the admin token — only reads files in the checkout. Self-
test step runs the unit tests on every invocation, so a regression
in the script can't false-pass on production.

Per BSD-vs-GNU portability hygiene: heredoc-marker extraction stays
in plain awk + sed (no gawk-only `match()` array form), grep regex
avoids `^` anchor for `if:` lines because real workflows use
`      - if:` with the `-` step-marker between leading spaces and
`if:` (the original anchor missed every workflow's per-step gates).
