fix(sdk): expose retrieval controls consistently

[ehz0ah]

Description

Expose the retrieval controls already accepted by the OpenViking server through the standalone Python and TypeScript SDKs.

The standalone Python SDK now supports since, until, time_field, level, and include_provenance on both find and search. The TypeScript SDK now supports includeProvenance, serialized as include_provenance.

Human Involvement

• A human participated in the implementation or review loop
• This PR was generated entirely by AI agents without human participation in the loop

Related Issue

No single issue covers the cross-SDK parity gap. Go provenance parity remains owned by #2731 and is intentionally not changed here.

Type of Change

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Refactoring (no functional changes)
• Performance improvement
• Test update

Changes Made

• Add time, level, and provenance retrieval options to standalone Python async/sync clients.
• Add includeProvenance to the TypeScript SDK and send the server's include_provenance field.
• Cover exact populated and unset request bodies so optional controls do not change existing defaults.

Testing

• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes
• I have tested this on the following platforms:
  • Linux
  • macOS
  • Windows

# passed
python -m compileall -q sdk/python/openviking_sdk sdk/python/tests/test_async_client_behaviors.py
# passed

ruff format --check reports pre-existing formatting differences elsewhere in the two touched Python files; this PR avoids unrelated whole-file formatting churn.

Additional Notes

The new Python parameters are appended to the existing signatures, preserving positional compatibility. Unset Python and TypeScript options are omitted from request bodies; explicit false remains representable for TypeScript provenance.
