Description:
Migrates the project to native ESM ("type": "module") and upgrades all major dependencies.

Changes

  • Set "type": "module" in package.json
  • Updated TypeScript config to module: NodeNext + moduleResolution: NodeNext
  • Updated all relative imports to use .js extensions (required for ESM)
  • Replaced .eslintrc.js + .eslintignore with flat config eslint.config.mjs
  • Replaced jest.config.js with jest.config.ts using ts-jest ESM mode
  • Updated test scripts to use --experimental-vm-modules
  • Updated ncc build output to ESM (dist/package.json → "type": "module")
  • Updated license files for new/changed transitive dependencies

Related issue:
Add link to the related issue.

Check list:

  • Mark if documentation changes are required.
  • Mark if tests were added or updated to cover the changes.

refactor: update imports to use ES module syntax and improve test str…

…ucture

- Changed import statements across multiple files to use the .js extension for ES module compatibility.
- Refactored test files to utilize jest's unstable_mockModule for mocking core actions.
- Removed unnecessary spy instances in tests, replacing them with direct mocked function calls.
- Updated TypeScript configuration to target ES2022 and use NodeNext module resolution.
- Removed the tsconfig.spec.json file and adjusted the main tsconfig.json to exclude test files.

Pull request overview

Migrates the action codebase to native Node.js ESM ("type": "module") and updates the toolchain (TypeScript, Jest, ESLint flat config) alongside major dependency upgrades to support newer @actions/* and @octokit/* versions.

Changes:

  • Switch TypeScript compilation to NodeNext ESM semantics and update codebase-relative imports to use .js extensions.
  • Replace Jest + ESLint legacy configs with ESM-compatible jest.config.ts and eslint.config.mjs, updating tests for ESM execution.
  • Upgrade runtime/dev dependencies and refresh/adjust third-party license metadata.
