Subject: [PATCH] ci: migrate CodeQL from default to advanced setup

The default setup only analysed a pull request when it touched files
relevant to the configured languages. A PR changing only docs or a
dependency manifest produced no analysis, while master still carried one
per language, so the code_scanning branch rule could not diff the two
sides and reported 'configurations not found'.

Add a codeql.yml with no path filter so both configurations exist on
every PR, keeping the /language:actions and /language:rust categories
recorded on master.

+# CodeQL advanced setup.
+#
+# Replaces the repository's CodeQL *default* setup, which only analyses a pull
+# request when it touches files relevant to the configured languages. A PR that
+# changes only docs or dependency manifests produced no analysis at all, while
+# `master` still carried one per language — so the `code_scanning` branch rule
+# could not diff the two sides and reported "configurations not found".
+#
+# Running here, with no path filter, guarantees both configurations exist on
+# every pull request. The categories below must keep matching the ones recorded
+# on `master` (`/language:actions`, `/language:rust`) for that diff to work.
