Secretlint CLI for Secret Detection

Secretlint is a powerful CLI tool designed for scanning codebases to detect and prevent the leakage of sensitive data like API keys, credentials, and private information. The current stable version is 12.2.0, with minor and patch releases occurring frequently, and major versions introducing breaking changes like Node.js engine requirements. It offers a highly extensible architecture through pluggable rules and presets (e.g., `@secretlint/secretlint-rule-preset-recommend`), supporting various file formats and offering multiple output formatters including `stylish`, `mask-result`, and `github` annotations. Key differentiators include its focus on precise secret detection, a flexible configuration system using `.secretlintrc` files, and the ability to mask secrets in output, making it suitable for CI/CD pipelines and pre-commit hooks.
