Pull Request Review: vers bump and ruff fix

Summary

This PR makes two small changes:

1. Bumps the version from 0.2.0 to 0.2.1 in src/chatan/__init__.py
2. Removes an unused import (Set) from src/chatan/async_dataset.py

---

Code Quality & Best Practices ✅

Positive:

• Clean removal of unused import - this aligns with Ruff's linting rules
• Version bump follows semantic versioning (patch version increment)
• Changes are minimal and focused

Suggestions:

• Consider adding a changelog entry (CHANGELOG.md) to document what changed in version 0.2.1
• The PR description is empty - it would be helpful to add context about why the version was bumped and what the Ruff fix addressed

---

Potential Bugs or Issues ✅

No bugs identified. The changes are safe:

• Removing unused Set import doesn't affect functionality since it wasn't being used
• Version string update is straightforward

---

Performance Considerations ✅

No performance impact. Removing unused imports has negligible (positive) impact on import time.

---

Security Concerns ✅

No security concerns with these changes.

---

Test Coverage 🔍

Observations:

• No tests were added or modified in this PR
• Based on the repo structure, there are existing tests but no test_async_dataset.py file was found
• The removed Set import suggests it may have been used previously and removed in earlier refactoring

Recommendations:

• If async_dataset.py doesn't have dedicated test coverage, consider adding tests/test_async_dataset.py to ensure the AsyncDataset class works correctly
• Verify that existing tests still pass with these changes (CI should catch any issues)

---

Additional Notes

The Set type was imported from typing but never used in the code. This was likely:

1. Left over from previous refactoring
2. Caught by Ruff linter (F401 - unused import)

The version bump to 0.2.1 suggests this is a patch release. Make sure:

• CHANGELOG.md is updated (if you maintain one)
• Git tag will be created for the release (v0.2.1)
• CI/CD pipeline passes all checks

---

Verdict: ✅ Approved

This is a clean maintenance PR that improves code quality by removing unused imports and bumping the version. The changes are minimal, safe, and follow best practices.

Recommendation: Merge after CI passes and consider adding a brief description to the PR for future reference.
