Levi Neuwirth bd728c4705 CUA region semantics — shift selection, region-aware delete + type-over ... - S-<arrows>/S-<home>/S-<end> (+C-S word/paragraph variants) extend a selection; the TUI grid paints it reverse-video; double-click selects the word at point. - Backspace / Delete consume the active region (delete_region first, falling back to single-codepoint semantics). - Typing replaces the region: buffer.self-insert / newline / tab delete_region before inserting. pmacs-gpu cooperates by round-tripping keys while an own-window selection is active, so the region-aware commands run instead of a raw optimistic op. - tests/cua_region_acceptance.rs drives the real dispatch path: select -> BS/DEL/char/Enter, plus the no-region fallbacks.
