chore: upgrade to typescript v6.0.2

[Tony133]

Proposal:

• Upgrade to typescript v6.0.2

• Changes made:

  • post-build.js:
    - Migrated from CommonJS (require) to ESM (import) syntax
    - Added fileURLToPath + import.meta.url to polyfill __dirname in ESM context
    - Added automatic creation of dist/cjs/package.json with { "type": "commonjs" } to ensure CJS output is correctly interpreted by Node.js
    - Fixed file extension mapping: CJS output now correctly renamed from .mjs → .cjs (and .d.mts → .d.cts)

  • tsconfig.json:
    - Added "module": "Node16" and "moduleResolution": "Node16" for proper dual CJS/ESM support

  • package.json:
    - Bumped typebox peer dependency from ^1.0.13 to ^1.1.14
    - Updated build:cjs script: switched --moduleResolution from Node10 to bundler
    - Fixed test:node script: now runs test/index.cjs instead of test/index.js
    - Added files field to control what gets published to npm (dist, index.ts)
    - Updated typescript devDependency from ~5.9.3 to ~6.0.2
    - Added "type": "module" and "module" field to package exports
    - Reorganized exports map: moved require condition after import

• Note:

  • eslint.config.cjs uses the .cjs extension because the package is now "type": "module".
  • TypeScript 6.x changed how module resolution works, requiring a dual CJS/ESM build setup to maintain compatibility with both import and require consumers.

This PR should resolve this PR: #272

import.meta.dirname is a thing.

[Tony133]

-import { fileURLToPath } from 'node:url'

-const __dirname = path.dirname(fileURLToPath(import.meta.url))
+const __dirname = import.meta.dirname

Yeah, we can do it that way too
