ci: unified org settings — lean tier contract (#7)

* ci: add CodeQL + Scorecard, harden lean CI for org ruleset contract

Phase 5 of unified org settings: lean tier repos require check names
`build` and `codeql` to match the org ruleset contract. Adds CodeQL
(javascript-typescript for docs JS), OpenSSF Scorecard via centralized
caller, and top-level permissions/concurrency to lean_action_ci.yml.
