Subject: [PATCH] Add CodeQL advanced setup workflow

Replaces CodeQL default setup with a committed workflow so analysis
runs on PR head commits (clearing the diff-informed "configurations
not found" warning) and the analysis config is version-controlled.

Both actions and rust use build-mode none (no compile required).
Categories match the previous default-setup categories for history
continuity.
