Pull request overview

This PR migrates actions/setup-java to ESM (to support newer @actions/* packages), updates the TypeScript/Jest/ESLint/Prettier configuration accordingly, and bumps dependencies with an accompanying major-version release note.

Changes:

Switch TypeScript output and internal imports to ESM-friendly NodeNext + explicit .js specifiers.
Replace legacy Jest/ESLint/Prettier configs with ESM/flat-config equivalents and update tests for ESM mocking.
Bump dependencies (including @actions/*) and update Licensed metadata; bump package version to 6.0.0 with README breaking-change note.

src/cleanup-java.ts:60

The ESM main-module check is brittle: process.argv[1] can be a relative path (e.g. node dist/cleanup/index.js) or differ by path normalization/symlinks, causing run() to be skipped even when this file is the entrypoint. Consider normalizing both sides (e.g., resolve process.argv[1] to an absolute path and compare to fileURLToPath(import.meta.url), or compare file URLs via pathToFileURL(path.resolve(process.argv[1]))).
