Add bulk document upload and pre-commit hook for knowledge base (#72)

## Summary

This PR introduces bulk document upload functionality to the
`DocumentClient` and adds a new model for document list items,
supporting the knowledge base feature. A Git pre-commit hook is also
added to enforce code quality checks before commits.

## Key Accomplishments

- **Bulk Document Upload**: Extended `DocumentClient` with a new method
to support uploading multiple documents in a single operation,
streamlining batch ingestion workflows for the knowledge base.
- **New Document List Item Model**: Added the `DocumentListItem` model
to represent individual documents within a collection, providing a
structured data type for list/bulk operations.
- **Pre-commit Hook**: Introduced a `.githooks/pre-commit` hook to
automate code quality checks as part of the local development workflow,
catching issues before they reach the remote repository.

## Changes Breakdown

| File | Change Type | Description |
|------|-------------|-------------|
| `robosystems_client/extensions/document_client.py` | Modified | Added
bulk upload method to `DocumentClient` |
| `robosystems_client/models/document_list_item.py` | Modified | Added
`DocumentListItem` model with document metadata fields |
| `.githooks/pre-commit` | Added | New pre-commit hook for automated
code quality enforcement |

## Breaking Changes

None. This is a purely additive change — existing APIs and models remain
unaffected.

## Testing Notes

- Verify that the new bulk upload method correctly handles multiple
document payloads and returns expected responses.
- Test edge cases for bulk uploads: empty lists, large batches, and
mixed valid/invalid documents.
- Confirm that `DocumentListItem` serializes and deserializes correctly
when used in API responses.
- Ensure the pre-commit hook executes successfully in a local
development environment and does not block valid commits.

## Infrastructure Considerations

- Developers should configure their local Git installation to use the
project's hooks directory to benefit from the newly added pre-commit
hook. This may require a one-time local setup step.
- The bulk upload endpoint should be evaluated for payload size limits
and timeout configurations on the server side to ensure it handles large
batch requests gracefully.
