security.yml: gitleaks secret scan + NuGet/npm vulnerability gate on PRs and
pushes to main/develop (detective backstop to the pre-commit hook).
deploy-staging.yml: on merge to develop, re-verify then rebuild the isolated
local staging stack (needs a self-hosted Windows runner).
deploy-prod.yml: tag-gated production promotion (the tag is the approval), ready
to activate once the Linux server + its runner exist.
