fix(ci): repair workflow(s) GitHub has never parsed

These files were rejected by the workflow parser before any run could be
scheduled: the API reported each name as its file path (the never-parsed
fallback), and every run failed at 0s with zero jobs and no logs.

- .github/workflows/secret-scanner.yml:ILLEGAL_KEY:rust-secrets:if-hashFiles

Validated per file: actionlint, yaml.safe_load, duplicate-key check.
