Subject: [PATCH] Add explicit GITHUB_TOKEN permissions to workflows
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Resolves the 10 open `actions/missing-workflow-permissions` CodeQL alerts
(#1, #6-#14) by giving every job an explicit least-privilege scope.

ci.yml: one workflow-level `contents: read`. All five jobs (ci-data,
rspec, rspec_ruby_version_file, static_type_check, notify_on_failure)
only check out the repo and run rake/srb, or post to a Slack incoming
webhook — none of them writes anything back to GitHub.

cd.yml: one workflow-level `contents: read` covering check-release
(sparse checkout + a rubygems.org version probe), ci-data
(oxidize-rb/actions/fetch-ci-data), build (checkout, cross-gem,
upload-artifact) and notify_on_release (Slack webhook). The `release`
job keeps its existing job-level `contents: write` override, which it
needs for `gh release create`; job-level permissions replace rather
than intersect the workflow-level block for normal jobs, so the release
path is unaffected.

stale.yml: job-level `issues: write` + `pull-requests: write` on the
shared-config caller. A caller's permissions are the ceiling for the
called workflow, and shared-config's stale.yml runs actions/stale,
which comments on and closes both stale issues and stale PRs.
