Updates github/codeql-action from 3.27.0 to 4.32.0

Release notes

Sourced from github/codeql-action's releases.

v4.32.0

  • Update default CodeQL bundle version to 2.24.0. #3425

v4.31.11

  • When running a Default Setup workflow with Actions debugging enabled, the CodeQL Action will now use more unique names when uploading logs from the Dependabot authentication proxy as workflow artifacts. This ensures that the artifact names do not clash between multiple jobs in a build matrix. #3409
  • Improved error handling throughout the CodeQL Action. #3415
  • Added experimental support for automatically excluding generated files from the analysis. This feature is not currently enabled for any analysis. In the future, it may be enabled by default for some GitHub-managed analyses. #3318
  • The changelog extracts that are included with releases of the CodeQL Action are now shorter to avoid duplicated information from appearing in Dependabot PRs. #3403

  • This update bumps the Scorecard version to the v5.1.1 release. For a complete list of changes, please refer to the v5.1.0 and v5.1.1 release notes.
  • Publishing results now uses half the API quota as before. The exact savings depends on the repository in question.
  • Some errors were made into annotations to make them more visible
  • There is now an optional file_mode input which controls how repository files are fetched from GitHub. The default is archive, but git produces the most accurate results for repositories with .gitattributes files at the cost of analysis speed.
  • The underlying container for the action is now hosted on GitHub Container Registry. There should be no functional changes.

posix_errors.v had two structural bugs:
1. Decision procedures declared as Axiom AFTER safe_* definitions that used them
   (forward-reference error in Coq's sequential processing).
2. safe_* definitions used `negb (sumbool_val)` which is a type error —
   negb : bool -> bool, but the sumbool {P} + {~P} is not a bool.

Fix:
- Moved decision procedures to BEFORE safe_* definitions.
- Proved path_exists_dec, is_directory_dec, is_file_dec,
  has_write_permission_dec, path_eq_dec constructively by case-splitting on
  the Filesystem function (Path -> option FSNode) and the FSNode fields.
- Kept is_empty_dir_dec as Axiom with full justification: universal
  quantification over an infinite-domain function cannot be decided
  constructively; finite-map refactor removes this axiom.
- Restructured safe_* definitions to use nested `if` on sumbool (correct)
  instead of `negb (sumbool_val)` (type error). All existing theorems and
  proofs preserved with minimal changes.

filesystem_composition.v: added detailed proof-strategy comments to
well_formed_ancestor_exists and mkdir_preserves_well_formed axioms,
referencing PROOF_HOLES_AUDIT.md items #1 and #2.

functional_extensionality: already correctly imported in filesystem_model.v;
all other files get it transitively via Require Import filesystem_model.

Convert well_formed_ancestor_exists and mkdir_preserves_well_formed from
Axiom to Lemma via strong induction on path length.

Add 6 helper lemmas: path_prefix_refl, path_prefix_length,
path_prefix_eq_of_same_length, path_prefix_app_invert, parent_path_lt,
path_prefix_parent — building the scaffolding described in PROOF_HOLES_AUDIT.md.

Fix path_prefix bool type: `path_prefix p child` (Prop mis-use) →
`path_prefix p child = true` throughout filesystem_model.v, posix_errors.v,
and filesystem_composition.v.

Fix rmdir_removes_path and mkdir_rmdir_reversible tactic sequences for Coq 8.20.

Switch _CoqProject from -Q to -R (recursive logical path mapping).

Add proofs/coq/.gitignore to exclude *.vo, *.vos, *.vok, *.glob, *.aux,
Makefile, Makefile.conf from version control.

Proof debt items #1 and #2 from docs/PROOF_HOLES_AUDIT.md are now CLOSED.
Coq layer: 0 Admitted, 1 justified Axiom (is_empty_dir_dec — infinite-domain
function, requires finite-map Filesystem refactor to eliminate).
