chore: update project for typescript to v6.0.2 and migrate type tests to tstyche

[Tony133]

Proposals:

• Upgrade typescript to v6.0.2 🔥
• Migrate type tests from tsd to tstyche 🔥
• Reorganize project structure 🔥

Changes made:

• package.json:

  • bumped typescript dev dependency from ~5.9.2 to ~6.0.2
  • update scripts for eslint

• replaced tsd with tstyche for type testing

• tsconfig.json: updated compiler options to align with TS6:

  • target: es6 → es2022
  • lib: ["es2015"] → ["es2022"]
  • module: commonjs → node16
  • moduleResolution: node → node16

• Type tests — restructured under types/:

  • index.d.ts → types/index.d.ts
  • index.test-d.ts → types/index.tst.ts (converted to tstyche)
  • import.test-d.ts → types/import.tst.ts (converted to tstyche)

• Project structure

  • logger.js → index.js
  • deprecations.js → examples/deprecations.js
  • example.js → examples/example.js
  • example-custom-format.js → examples/example-custom-format.js
  • test/test.js — updated imports to reflect new paths

Note:

• This PR should resolve this PR: https://github.com/pinojs/pino-http/pull/
• new project structure ( see screenshot )
