fix: add word-wrap function, complete TUI migration

- Add missing word-wrap function (was declared in contract but never defined)
- TUI now renders correctly: draw-text on framebuffer arrays works
- Daemon connection verified
- All three view functions (status, chat, input) call draw-text correctly
