Fix Score.as_dict() to include name field

[Alex Jean-Baptiste (justcodebruh)]

Summary

Fixes a bug in Score.as_dict() where the name field was missing when serializing, causing "Object of type Score is not JSON serializable" errors when returning Score objects from Python scorers.

Problem

The API expects Score objects to have name, score, and metadata fields, but as_dict() was only returning score and metadata. This caused the following error when using online scorers:

Cannot log [{"name":"...","score":1,"metadata":{...}},...] as a score
Object of type Score is not JSON serializable

Solution

Updated Score.as_dict() to include the name field:

def as_dict(self):
    return {
        "name": self.name,        # ← ADDED
        "score": self.score,
        "metadata": self.metadata,
    }

Changes

• Updated py/src/braintrust/score.py: Fixed Score.as_dict() method
• Added py/src/braintrust/test_score.py: Comprehensive test suite with 10 tests

Tests

All 10 new tests pass:

• ✅ All required fields are included in serialization
• ✅ JSON serialization works correctly
• ✅ Round-trip serialization/deserialization
• ✅ Arrays of Score objects serialize correctly
• ✅ Edge cases (null scores, empty metadata, complex metadata)
• ✅ Score validation bounds checking

LGTM -- reproduced this on a local playground and this patch fixed the issue with a python remote scorer
