Repin organization lock actions to v1.16.0

[ambiguous-build-lock-automation]

Repin the organization lock actions to the authorized release v1.16.0
(84b8d875ab1968716ef95b5b56d10307609237ca).

Review before merge (leaving auto-merge on is the adoption decision)

• Only the @<sha> suffix of uses: references to
  Ambiguous-Interactive/ambiguous-organization-build-lock changed, plus # vX.Y.Z version comments
  (updated or added).

• Reviewed companion artifacts named in the enrollment policy carry the
  consumer files that derive from the pin. Each one moves through one
  mechanical, mode-bound rewrite.

• Release authorization evidence: the central authorization pull request for
  this release, merged by a maintainer.

• The automation enables auto-merge on this pull request. The merge then
  fires only when every required check and merge rule passes. Disable
  auto-merge on this pull request to merge by hand instead.

• Changed references:

- `.github/workflows/perf-numbers.yml` (10 lines)
- `.github/workflows/release.yml` (7 lines)
- `.github/workflows/runner-bootstrap.yml` (1 line)
- `.github/workflows/unity-benchmarks.yml` (7 lines)
- `.github/workflows/unity-tests.yml` (9 lines)

Reviewed companion artifacts

These policy-reviewed files derive their content from the pin. Each changed
file moved through its reviewed mechanical rewrite:

• docs/ops/ambiguous-release-migration.md (pin-lines)
• docs/ops/ci-and-github-settings.md (pin-lines)

Central automation opens this pull request and enables auto-merge. It never
edits a default branch and never force-pushes.
