Fixed numerous bugs

[sn]

This pull request introduces several improvements and fixes to the nitro-datastore package, focusing on enhanced error handling, improved efficiency, and minor documentation and versioning updates. The most significant change is the addition of a strict mode to the from_directory method, allowing users to control how invalid JSON files are handled during directory loading.

Error Handling & API Improvements:

• Added a strict parameter to the NitroDataStore.from_directory method, enabling users to choose whether invalid JSON files should raise exceptions or be skipped silently. The method's docstring and exception documentation were updated accordingly. [1] [2] [3] [4] [5]

Performance & Code Quality:

• Optimized the diff method in NitroDataStore by creating a single NitroDataStore instance for the other argument, reducing redundant instantiations and improving efficiency.
• Fixed a bug in QueryBuilder.first() where the limit was not reset after execution, ensuring correct behavior for subsequent queries.

Versioning:

• Bumped the package version from 1.0.2 to 1.0.3 in pyproject.toml.
