v0.2.0

What's Changed

Features & Fixes

• Surgical string replacement — preserves Python comments by using AST-based offset replacement instead of full-cell rewriting (#2)
• Dropped astor/black dependencies — simplified formatter pipeline

Testing

• Fixture-based eval suite — 15 auto-discovered test cases covering SQL pattern breadth (CTEs, joins, window functions, unions, etc.) and notebook scenarios (magic commands, f-strings, idempotency, comment preservation)
• Added comment-preservation unit test

Infrastructure

• Pre-commit dev config with ruff linting/formatting
• CI: trusted publishers for PyPI, updated to actions/checkout@v4
• Modernized consumer pre-commit hook
