Fix #926: Enable CodeQL security scanning

[anshu10sep]

Summary

Adds CodeQL security scanning to the CI pipeline for automated vulnerability detection in Kotlin/Java code.

Problem

The repository lacked automated security scanning. CodeQL can detect common vulnerability patterns like SQL injection, path traversal, and unsafe deserialization.

Changes

• .github/workflows/codeql.yml (NEW): CodeQL workflow that runs on push to main and on PRs, scanning Kotlin and Java source code.

Configuration

• Triggers: push to main, pull requests targeting main
• Languages: java-kotlin (covers both Kotlin and Java)
• Build: autobuild mode (auto-detects Gradle)
• Queries: security-and-quality (extended query suite)

Validation

• YAML syntax validated
• Workflow follows GitHub Actions best practices

Fixes #926

You are seeing this message because GitHub Code Scanning has recently been set up for this repository, or this pull request contains the workflow file for the Code Scanning tool.

What Enabling Code Scanning Means:

• The 'Security' tab will display more code scanning analysis results (e.g., for the default branch).
• Depending on your configuration and choice of analysis tool, future pull requests will be annotated with code scanning analysis results.
• You will be able to see the analysis results for the pull request's branch on this overview once the scans have completed and the checks have passed.
