Refactor workflows

[javidahmed64592]

This pull request updates the GitHub Actions CI workflows to improve consistency, modularity, and support for both Python and Node.js projects. The workflows now use a standardized set of reusable actions for setting up environments and running checks, and they have been refactored for better maintainability and extensibility.

Key workflow improvements:

Workflow standardization and modularization:

• Replaced custom job names and steps with a consistent set of reusable actions for Python environment setup (setup-uv-python, install-python-dev, etc.) and checks, making the workflows easier to maintain and extend. (.github/workflows/ci.yml, .github/workflows/build.yml, .github/workflows/docs.yml) [1] [2] [3]
• Refactored job names and consolidated related checks (e.g., linting, type checking, security analysis) under unified jobs like python-code-check, python-security-check, and python-validate. (.github/workflows/ci.yml)

Node.js/Frontend support:

• Added conditional Node.js setup and jobs (npm-code-check, npm-tests) that only run if a frontend directory exists, enabling support for hybrid Python/Node.js projects. (.github/workflows/ci.yml)

Documentation and build process improvements:

• Updated the docs and build workflows to use the new Python setup actions, ensuring consistent environment preparation for documentation builds and wheel builds. (.github/workflows/build.yml, .github/workflows/docs.yml) [1] [2]

These changes make the CI/CD pipeline more robust, modular, and ready for projects with both backend and frontend components.
