Add codeql config to fix languages that no longer exist

[cmmarslender]

Note

Low Risk
Low risk: adds a GitHub Actions workflow for CodeQL scanning only, with no application code or runtime behavior changes.

Overview
Adds a new GitHub Actions workflow (.github/workflows/codeql.yml) to run CodeQL Advanced scanning on pushes and PRs to main, plus a weekly scheduled run.

The workflow analyzes actions, python, and rust via a matrix strategy, initializes and runs github/codeql-action v4, and includes a stub manual-build step for any future manual build modes.
