Code Review Comments Block for Radix UI

Edit RAW_ROWS (a change of add, remove or context, and the text) and START for the threads: each has a row number, its remarks and an optional suggestion for that row. Row numbers are the position in the diff. Resolved threads are listed in START_RESOLVED.

It replaces the row's text with the suggestion, resolves the thread and moves focus to the thread's Reopen button, and the status line says which row changed. Apply then reads Applied and does nothing more. Copy puts the suggested row on the clipboard if the browser allows it and says so if it does not.

The diff, the threads, the applied suggestions and the review. Submit review only says Review submitted in this demo. To make it real, send comments and resolutions to your review API, apply suggestions as commits on the server and compute the review state from the open threads there.

Code keeps one reading direction whatever language the page is in, so the rows are marked that way and sit unchanged inside a layout that flips for right-to-left languages. Names and counts around them are isolated so mixed text keeps its order.

Each row number is a button named for what it does (Comment on row 9, Reply on removed row 3) and reports whether its composer is open. Added and removed rows are written in hidden text as well as shown with a glyph, so colour is never the only signal. Focus moves into a new composer, back to the row after Cancel or a post, and to Reopen after Apply.

The row numbers stay, long lines wrap instead of scrolling, and thread cards go full width under their row. The window keeps its height and only the diff scrolls.
