Purpose

This pull request introduces significant improvements to the GitHub Actions workflows by adding precise path-based triggers to all workflow YAML files. This ensures that workflows only run when relevant files are modified, leading to faster CI/CD feedback, reduced unnecessary runs, and clearer PR status checks. Additionally, comprehensive documentation has been added to explain the workflows and their triggers.

Workflow path trigger enhancements:

• Added paths filters to all major workflow YAML files (deploy.yml, docker-build-and-push.yml, test.yml, pylint.yml, codeql.yml) to ensure each workflow only runs when files it actually uses are changed. This reduces unnecessary CI runs and improves performance. [1] [2] [3] [4] [5] [6]

Documentation updates:

• Added a new, detailed docs/GitHubActionsWorkflows.md file that documents all workflows, their triggers, path filters, purposes, and recent optimizations. This helps team members understand when and why workflows run, and how to maintain them.

Other changes:

• Added a placeholder line to infra/hello.md (likely for testing or as a stub).
