Subject: [PATCH] ci(codeql): add Rust CodeQL coverage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

security.yml declares languages '["actions"]', so CodeQL analysed only the
workflow files under .github/ — the on-chain Rust in resq-airspace/,
resq-delivery/ and resq-gating/ had no coverage. Code-scanning default setup
is not-configured on this repository and does not cover Rust here either.

Adds a dedicated advanced-setup workflow pinned to codeql-action v4.38.1 with
languages: rust, mirroring the equivalent workflow in the crates repository,
which uploads /language:rust analyses successfully today.

+# CodeQL coverage for this repository's Rust sources.
+#
+# Why this file exists, and why it is separate from security.yml:
+#
+#   * security.yml calls the org reusable security-scan with
+#     `languages: '["actions"]'`, so CodeQL analysed only the workflow files
+#     under .github/. The on-chain Rust in resq-airspace/, resq-delivery/ and
+#     resq-gating/ had no CodeQL coverage at all.
+#   * GitHub code-scanning *default setup* is `not-configured` on this
+#     repository, so nothing was covering Rust implicitly either.
+#   * The reusable revision that security.yml pins carries
+#     `continue-on-error: true` on its CodeQL analyse step (it tolerates a
+#     default-setup collision on other repos). Routing Rust through that
+#     caller would let a genuine Rust extraction failure pass as green and
+#     leave this repository looking scanned when it was not — so Rust gets a
+#     caller of its own, with failures left visible.
+#
+# This mirrors the equivalent workflow in the `crates` repository, which has
+# been uploading `/language:rust` analyses successfully.
