revdiff adds Jujutsu repository support

The interesting part here is not just “AI review,” it’s VCS compatibility: jj support turns revdiff from a Git-first novelty into a more credible review layer for modern local workflows.

• –revdiff already positions itself as a review TUI for AI agents, Claude Code, and Codex; jj support removes a real adoption blocker
• –auto-detecting jj in colocated repos matters because a lot of developers use jj specifically to avoid Git friction in day-to-day review loops
• –the Codex plugin angle is the real wedge: it keeps the human-in-the-loop review flow while pushing annotation and fixes back into the agent loop
• –this is a small feature with outsized reach, because review tools get much more useful once they stop assuming one VCS
• –if you’re migrating a team to jj, tooling like this is what makes the switch feel operationally complete rather than experimental
