Subject: [PATCH] ci: add CodeQL static analysis

- New codeql.yml with manual build mode for C/C++ analysis
- Uses security-extended query suite, triggers on push/PR to master plus weekly schedule
- Upgraded to CodeQL Action v4 with full SHA pins
- Permissions scoped to contents: read and security-events: write
- Pin runner to ubuntu-24.04, add setup-python for PEP 668 compatibility, add job timeout
