[alexey1312]

Description

Refactors the GitHub Action from JavaScript/shell to TypeScript with full type safety, adds ESLint and Prettier for code quality, and introduces Jest for unit testing.

• Migrate core logic to TypeScript (src/index.ts, src/types.ts)
• Add ESLint + Prettier configuration for linting and formatting
• Add Jest with unit tests for output parsing and error handling
• Update CI workflows for build and test automation
• Add hk.pkl for pre-commit hooks configuration

Summary of Changes

Hello @alexey1312, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request represents a significant refactoring of the GitHub Action, transitioning its entire implementation from a shell-script-based composite action to a TypeScript-based Node.js action. This change aims to improve the action's robustness, testability, and long-term maintainability by leveraging modern JavaScript tooling and practices. The update also introduces a more structured development environment with integrated linting, formatting, and unit testing, ensuring higher code quality and a more efficient contribution process.

Highlights

• Core Logic Migration to TypeScript: The GitHub Action's core logic has been completely rewritten from shell scripts to TypeScript, enhancing type safety, maintainability, and developer experience. This includes new files like 'src/index.ts' for the main logic and 'src/types.ts' for type definitions.
• Introduction of ESLint and Prettier: New configurations for ESLint and Prettier have been added ('eslintrc.json', '.prettierrc') to enforce consistent code style and identify potential issues, integrated into the development workflow via 'hk.pkl' and 'package.json' scripts.
• Unit Testing with Jest: Jest has been integrated for unit testing, with a new configuration ('jest.config.js') and initial unit tests ('src/index.test.ts') covering key functions like output parsing, error categorization, and command building.
• GitHub Action Definition Update: The 'action.yml' file has been updated to reflect the new architecture, switching from a 'composite' shell-based run to a 'node20' runtime that executes the compiled 'dist/index.js' file. All previous shell steps have been removed.
• Streamlined Development Workflow: The 'mise.toml' file and new 'package.json' scripts consolidate development tasks for linting, formatting, testing, and building, simplifying the local development and CI processes. A new 'CONTRIBUTING.md' guide has also been added.
