Pull request overview

This PR streamlines the repo’s tooling by removing unused packages, migrating several internal scripts from CommonJS/JS to ESM/TypeScript, and updating local + CI workflows to use the new setup (including switching git hooks from Husky to Lefthook).

Changes:

• Remove unused dev dependencies and update yarn.lock accordingly; add Lefthook and newer Node typings.
• Convert scripts to ESM/TypeScript (generate-mappings, typescript-output-lint, generate-ts-tests, component docs generator) and update call sites.
• Update CI, docs, ESLint config/ignores, and tests to match the new scripts and reduceMotion usage.
