Fix CodeQL workflow by removing non-existent Actions language analysis

[Copilot]

The dynamic CodeQL workflow failed attempting to analyze GitHub Actions code that doesn't exist in this repository, which only contains JavaScript/TypeScript.

Changes

• Added explicit CodeQL workflow (.github/workflows/codeql.yml)
  • Language matrix: javascript-typescript only
  • Standard triggers: push/PR to main/develop, weekly schedule
  • Removes default setup's erroneous actions language configuration

strategy:
  fail-fast: false
  matrix:
    language: [ 'javascript-typescript' ]

This overrides the GitHub-managed dynamic workflow that was misconfigured with Actions language analysis.

Original prompt

The CodeQL workflow failed because it tried to analyze GitHub Actions code, but no such code exists in the repository. To fix this, update the CodeQL workflow file ('dynamic/github-code-scanning/codeql') so that only JavaScript and TypeScript are set as languages to analyze. Specifically, remove 'actions' from any language lists or matrix definitions. Example fix:

matrix:
language: [javascript, typescript]

If the configuration specifies languages directly, ensure only present languages are listed. Remove steps or config for analyzing GitHub Actions if no custom Actions exist. After updating, CodeQL should successfully scan the repo for JavaScript/TypeScript but not Actions.
