* feat(validation): Support array indexing in JSON path validation (#21)

* feat(validation): Support array indexing in JSON path validation

- Updated the JSON path validation regex to allow array indexing (e.g., `$.data[0].attribute`).
- Ensured compatibility with dot notation for nested objects (e.g., `$.data.object.attribute`).
- Improved validation to support mixed array and object paths (e.g., `$.data[0].nested[2].value`).
- Added stricter checks to prevent malformed paths.

* update engine version
