Summary

Rename Pydantic Canary to Bumpcheck before the old identity becomes established. This also closes two comparison gaps that could hide runtime drift: Python equality treated 1, 1.0, and true as equivalent, and Pydantic validation errors ignored field locations.

Changes

• Rename the distribution, import package, and primary command to bumpcheck, while retaining a temporary pydantic-canary command alias.
• Compare canonical JSON representations in top-level and batch results.
• Compare stable Pydantic validation error type and loc records.
• Keep worker result JSON separate from Python, native, and child-process output.
• Replace the repository-only quickstart with a clean-directory workflow and document --with . for local projects.
• Add a CI regression using Pydantic 2.10.6 and 2.11.1.

Validation

• 61 unit tests pass on Python 3.10 through 3.14.
• Branch coverage is 96%.
• The real Pydantic 2.10.6 to 2.11.1 regression is detected.
• The built wheel passes metadata and contents checks.
• Tracewright's four-record JSONL consumer remains unchanged across Pydantic 2.10.0 and 2.13.4.

Repository rename and PyPI publication are deliberately not part of this PR.
