Pull request overview
This PR fixes a bug where OData annotation keys were being incorrectly lowercased. The _lowercase_keys helper function now preserves case-sensitive OData keys (like @odata.bind) while still normalizing Dataverse attribute names to lowercase.
Changes:
- Modified
_lowercase_keysto detect and preserve OData annotation keys by checking for "@OData" substring - Updated docstrings and inline comments to reflect the new behavior

The _lowercase_keys function lacks test coverage for the new behavior of preserving OData annotation keys. Consider adding tests that verify OData keys like "@odata.bind", "@odata.type", and "@odata.nextLink" are preserved with their original casing while regular attribute keys are lowercased.

The _lowercase_keys helper function previously lowercases all string keys which unintentionally breaks OData keys such as @odata.bind. These keys are case sensitive and must remain unchanged for Dataverse to interpret them correctly.
