Review pull request $ARGUMENTS.

1. Fetch the PR metadata and diff via gh pr view and gh pr diff.
2. If the PR branch isn't already checked out locally, run jj git fetch and jj new <branch> to get it.
3. Summarize what the PR does and why.
4. Analyze the architecture and check whether this change could have been achieved in a simpler or more idiosyncratic way.
5. Perform an adversarial review: actively try to break the code. Look for logic errors, incorrect assumptions, edge cases, silent failures, security holes, race conditions, and performance traps. Only report real, substantiated issues with file:line references — not hypotheticals or linter-level nitpicks.
