ci: make required status checks reportable on every PR

Four branch-protection-required checks sit permanently at "Expected —
Waiting for status to be reported" because the contexts they pin are only
conditionally produced:

- analyze (actions, none)                  codeql.yml gated to base main/master
- hypatia / Hypatia Neurosymbolic Analysis hypatia-scan.yml gated to base main/master
- Hypatia                                  GitHub App check (rides on the scan)
- governance / Validate Hypatia baseline   emitted by the standards governance
                                           reusable; this repo runs a standalone
                                           `governance` job (#603/#604) instead

This fixes the repo-side of the mismatch:

* codeql.yml / hypatia-scan.yml: drop the pull_request `branches:[main,master]`
  filter so the required jobs run on PRs against every base. A required check
  whose workflow is branch-filtered is never created, so it blocks forever.
* Add governance-baseline.yml + governance-baseline-impl.yml: a LOCAL reusable
  (no cross-repo @main coupling, no BP008 concurrency collision) whose
  `governance` / "Validate Hypatia baseline" job re-emits the pinned context
  name without disturbing the standalone governance gate. Additive: the repo
  now emits both `governance` and `governance / Validate Hypatia baseline`.

The `Hypatia` app check and any other pinned `governance / *` sub-checks remain
a branch-protection reconciliation (repoint pins to emitted names) needing
repo-admin access; documented in the PR.

+#
+# Why this exists
+# ---------------
+# Branch protection pins `governance / Validate Hypatia baseline` as a required
+# status check. That exact context name is produced by the shared
+# `hyperpolymath/standards` governance *reusable* — the check name of a
+# reusable job is `<caller-job-id> / <reusable-job-name>`, i.e.
+# `governance` + "Validate Hypatia baseline".
+#
+# This repo migrated its governance gate OFF that reusable to a standalone job
+# (`governance.yml` -> tools/ci/governance-standalone.sh, #603/#604) to escape
+# the cross-repo `@main` coupling and the BP008 reusable-caller startup
+# failure. The standalone job emits the context `governance` instead, so the
+# pinned `governance / Validate Hypatia baseline` was never reported again and
+# sat permanently at "Expected — Waiting for status to be reported".
+#
+# This workflow reproduces JUST that context name through a *local* reusable
+# (no cross-repo coupling, so none of the BP008 risk that motivated #603/#604),
+# leaving the standalone `governance.yml` gate untouched. It is additive: the
+# repo now emits both `governance` and `governance / Validate Hypatia baseline`.
+#
+# The cleaner long-term fix is to repoint the branch-protection pin to the
+# emitted name (`governance`); this bridge makes the merge box go green without
+# requiring repo-admin access to edit branch protection.
