feat: add getProcessInfo tool to retrieve BPMN representation of a process

- Implemented a new tool `getProcessInfo` that fetches the BPMN representation of a process based on the provided process ID.
- Added Zod schema for input validation.
- Defined tool metadata including name, description, and hints for usage.
- Updated dependencies in yarn.lock to include new versions and additional packages.
