Adds a CI job that runs the zizmor static analyzer over the workflow files under .github/, and applies the corresponding hardening so the existing workflows pass the audit: - add persist-credentials: false to every actions/checkout step that lacked it - narrow top-level permissions: read-all to permissions: contents: read - add a 7-day cooldown to the dependabot update entries This is a CI/configuration-only change; no library code, tests, or documentation are affected.

zizmor flagged three medium-severity template-injection findings where workflow_call string inputs were expanded directly inside run: blocks. Route each flagged input through an env: var and reference it as a shell variable so no untrusted value is interpolated into the script text.

.github/.zizmoraudits GitHub Actions workflows for supply-chain and privilege-escalation weaknesses — unpinned action references, credential persistence through the checkout token, template injection via${{ ... }}expansion inrun:blocks, and overly broadGITHUB_TOKENpermissions.Alongside the new scan, this applies the corresponding hardening to the existing workflows so they pass the audit:
