feat: expose Data Designer run config

[lipikaramaswamy]

Summary

Adds an optional data_designer_run_config parameter to Anonymizer(...) so callers can configure Data Designer runtime controls such as buffer_size and max_in_flight_tasks while still using Anonymizer's normal model config/provider loading path.

The name is intentionally explicit: it sits next to the existing advanced data_designer constructor parameter and avoids overloading run_config, which could be confused with AnonymizerConfig or anonymizer.run(config=...).

This keeps execution/backpressure tuning on the runtime constructor instead of putting it on AnonymizerConfig, which remains focused on anonymization behavior. The PR also re-exports RunConfig from anonymizer so examples can use the public Anonymizer import path.

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update
• Refactoring

Testing

• make test passes locally
• make check passes locally (format + lint + typecheck + lock-check)
• Added/updated tests for changes

Targeted validation run:

• uv run pytest tests/interface/test_anonymizer_interface.py -q
• uv run ruff check src/anonymizer/interface/anonymizer.py tests/interface/test_anonymizer_interface.py

Documentation

• If docs changed: make docs-build passes locally

No docs changed. This small API hook is intended to support self-hosted Data Designer runtime/backpressure configuration without bypassing Anonymizer's provider setup.

Greptile Summary

This PR exposes Data Designer's runtime execution controls (buffer_size, max_in_flight_tasks) through a new optional data_designer_run_config: RunConfig | None parameter on Anonymizer.__init__. RunConfig is also re-exported from the top-level anonymizer package so callers can import it from a single public path.

• src/anonymizer/interface/anonymizer.py: Adds data_designer_run_config parameter; calls self._data_designer.set_run_config(...) after the DataDesigner instance is created/assigned and before adapters are wired up, which is the correct ordering.
• src/anonymizer/__init__.py: Re-exports RunConfig as a first-class public symbol alongside ModelProvider.
• tests/interface/test_anonymizer_interface.py: Adds two focused unit tests — one for the Anonymizer-managed DataDesigner path and one for the caller-supplied DataDesigner path — using Mock(spec=DataDesigner) to exercise both branches.

Confidence Score: 5/5

Safe to merge — the change is a small additive parameter with no impact on existing call sites.

The new parameter is optional and defaults to None, so all existing Anonymizer(...) call sites are completely unaffected. The set_run_config call is placed after DataDesigner construction and before adapter wiring, which is the correct ordering. Both code paths (managed and caller-supplied DataDesigner) are exercised by dedicated unit tests. The RunConfig re-export keeps the annotation runtime-resolvable, which was carefully verified in the prior review thread.

No files require special attention.

Important Files Changed

Filename	Overview
src/anonymizer/interface/anonymizer.py	Adds data_designer_run_config parameter; applies it to the DataDesigner instance in the correct order (after construction, before adapter wiring). No logic regressions found.
src/anonymizer/init.py	Re-exports RunConfig from data_designer.config.run_config eagerly, keeping it runtime-resolvable for typing.get_type_hints() — correct given from future import annotations is in anonymizer.py.
tests/interface/test_anonymizer_interface.py	Two new tests cover both the managed and caller-supplied DataDesigner paths; uses spec=DataDesigner to catch missing method errors at mock time.

Looks good.
