* feat: add JSONPathExtractor tool with lodash-based path extraction

  - Implement JSONPathExtractor tool for extracting values from JSON using path notation
  - Use lodash.get for robust path extraction supporting edge cases (numeric string keys, array indexing)
  - Add configurable error handling with returnNullOnError parameter
  - Include comprehensive test suite with 34 tests covering all scenarios
  - Support JSON strings, objects, and arrays as input

* fix lint

* Update pnpm-lock.yaml
