Updates the project to newer runtime/tooling (Node 26, TypeScript 6) and aligns parsing/traversal logic with the upgraded oxc-parser API, while tightening local and CI automation for lint/type-check/test.

Changes:

• Drop Node 20 support; bump package major version and update Node engine/CI matrices to Node 22/24/26.
• Upgrade key dependencies/devDependencies (notably oxc-parser, TS, ESLint) and adjust src/format.ts to use oxc-parser’s Visitor.
• Add Husky + lint-staged wiring and minor TypeScript compiler option updates.
