refactor(py): sync optional file payload default behavior

[chyroc]

Summary

• Sync generated SDK output after coze-sdk-gen removed files_expr mapping support.
• Keep equivalent behavior for optional single-file payloads by checking file is not None before constructing files.
• Updated generated file:
  • cozepy/audio/voiceprint_groups/features/__init__.py
• Added tests to cover the new optional-file branch in both sync and async clients:
  • tests/test_audio_voiceprint_groups_features.py

Upstream

• coze-sdk-gen PR: refactor(codegen): remove files_expr config support coze-sdk-gen#59

Validation

• ./scripts/genpy.sh --output-sdk /tmp/coze-py-DfIlej --ci-check (executed in codegen workflow)
• poetry run pytest tests/test_audio_voiceprint_groups_features.py

📝 Walkthrough

Walkthrough

The PR modifies file validation in VoiceprintGroupsFeaturesClient's update methods (both sync and async variants) by changing from a falsy check to an explicit None check, allowing empty/falsy file values to proceed through file attachment logic instead of being skipped.

Changes

Cohort / File(s)	Summary
File Validation Logic cozepy/audio/voiceprint_groups/features/__init__.py	Changed file presence guard from truthiness check (if file) to explicit None check (if file is not None) in both VoiceprintGroupsFeaturesClient.update and AsyncVoiceprintGroupsFeaturesClient.update methods.

Poem

A rabbit checks with care so true,
Not just for presence, but what's new—
None means nothing, falsy means vague,
Being precise wins every plague! 🐰✨
