refactor(tui): rombak renderer ke OpenTUI React bindings
Ganti renderer ANSI line-based (render.ts) dan event loop raw stdin dengan
OpenTUI React bindings (@opentui/react + @opentui/core, React 19.2):
- ui.tsx: komponen ZesdexApp (header/scrollbox transkrip/input/footer),
adaptor toControllerKey (OpenTUI KeyEvent -> controller KeyEvent),
bootTui (createCliRenderer + createRoot + mount).
- run.ts: pakai bootTui, jalankan OpenTUI sampai user quit.
- state/action/command/controller tetap logika murni (tidak tersentuh).
- 5 unit test baru untuk toControllerKey; 79 test total hijau.
- tsconfig: jsx react-jsx + jsxImportSource @opentui/react.
- hapus render.ts (tidak terpakai); hapus script format rusak (bun fmt).
- deps: @opentui/core, @opentui/react, react, @types/react.
verify: tsc 0 err, bun test 79 pass, dist/zesdex merender TUI via pty.
