Commit Message

perf(ui): index visual rows for page navigation

Page motions repeatedly recalculated the cursor's visual position from the start of the diff and rebuilt hunk and annotation metadata for every cursor step. This made PgUp, PgDown, Ctrl-U, and Ctrl-D increasingly expensive deeper into large files.

Build one visual-row index per page motion and reuse precomputed hunk and annotation state while preserving wrap, collapsed, and annotation semantics. A 10,000-line benchmark drops from roughly 233 ms to 48 ms per page motion.
