[voxpelli]

This pull request introduces several updates to modernize the project, improve automation, and enhance test reliability. Notably, it upgrades Node.js and dependency requirements, migrates to the new flat ESLint config, adds automated release and compliance workflows, and improves test output normalization. Below are the most important changes grouped by theme:

Automation & CI/CD Improvements

• Added GitHub Actions workflows for automated releases (release-please.yml) and compliance checks (compliance.yml), and configured release-please with custom changelog sections and manifest tracking. (.github/release-please/config.json [1] .github/release-please/manifest.json [2] .github/workflows/release-please.yml [3] .github/workflows/compliance.yml [4]
• Updated Node.js test matrix to include versions 20, 22, 24, and 25 for broader compatibility testing. (.github/workflows/nodejs.yml .github/workflows/nodejs.ymlL20-R20)

Dependency & Engine Upgrades

• Increased minimum supported Node.js version to 20.19.0 (dropping support for Node 18), and updated both runtime and development dependencies to their latest major versions. (package.json [1] cli-wrapper.cjs [2]
• Updated the CLI to use node:path as pathModule for compatibility with newer Node.js versions. (cli.js [1] [2]

Linting Configuration Modernization

• Migrated from legacy .eslintrc to the new flat config (eslint.config.js), and removed unnecessary ESLint plugins and options from scripts. (.eslintrc [1] eslint.config.js [2] package.json [3]

Test Robustness Improvements

• Enhanced test helpers and output normalization to consistently strip ANSI color codes, ensuring reliable assertions across environments. (test/helpers.js [1] [2] test/test-readme.js [3]

Code Quality & Minor Fixes

• Added targeted ESLint disables for specific lines to address code style and security plugin warnings. (test/integration.js [1] test/test-readme.js [2]

These changes collectively improve the maintainability, automation, and reliability of the project.
