Fetch PR Diff

Fetches a pull request diff and adds line numbers for easier review-comment placement. Auto-generated files (lock files, protobuf-generated Java) are shown with masked diffs so review focuses on hand-written changes.

Usage

uv run "${CLAUDE_SKILL_DIR}/scripts/fetch_diff.py" <pr_url> [--files <pattern> ...]

The script is a self-contained PEP 723 script — uv run resolves its dependencies on demand; no install step is needed.
