Make review chat appear beside the PR diff instead of opening a new tab

Describe the request

When reviewing a PR, opening a side chat should open a sidebar panel next to the same diff view, so you can ask questions about the change while still looking at the file.

Today, opening a side chat creates a new tab and takes you away from the diff. Graphite keeps chat adjacent to the diff so review + AI stay on one screen.

Why this matters
Someetimes PR review is a “look at the change + ask about it” loop for me. Losing the diff when chat opens breaks that loop.

Ideal behavior
Chat opens as a resizable pane beside the diff container (same layout shell)
Optional: “Ask about this hunk / selection” that quotes the selected diff into that side chat

Reference UX
Graphite PR review: chat panel that stays beside the diff, not a separate tab

Hey @Ian_T!

Agreed that it’s a shame the diff doesn’t stick around, gets replaced by the side chat interface. I reproduced this locally, recorded a vid, and shared your feedback with the team!
