Use the active DiffState, native FilePicker and existing diff input, layout, focus, source navigation and scrolling paths for Resolution. Delete separate resolver filtering, file-list rendering and scroll APIs. Keep projections, source choices, History and guarded jj saves distinct. Verify native parity for picker remaps, current-file selection, excerpt initialization, folded search, wheel focus, layouts, buffer transitions and per-file viewports. All 932 tests pass; actual terminal smoke covers Space-e explorer, Down/Enter file selection and guarded confirmed save. Clippy completes with existing warnings only. Size exception: 1197 implementation added/deleted lines excluding tests and docs; input routing, native buffer lifecycle and rendering are kept as one coherent cutover, without a parallel legacy resolver path.
