Fix: Shift + Enter no longer prints “[27;2;13~” in the single‑line
input. Validated as working and necessary in Ghostty on Linux.
## Key points
- src/components/vendor/ink-text-input.tsx
- Added early handler that recognises the two modifyOtherKeys
escape‑sequences
- [13;<mod>u (mode 2 / CSI‑u)
- [27;<mod>;13~ (mode 1 / legacy CSI‑~)
- If Ctrl is held (hasCtrl flag) → call onSubmit() (same as plain
Enter).
- Otherwise → insert a real newline at the caret (same as Option+Enter).
- Prevents the raw sequence from being inserted into the buffer.
- src/components/chat/multiline-editor.tsx
- Replaced non‑breaking spaces with normal spaces to satisfy eslint
no‑irregular‑whitespace rule (no behaviour change).
All unit tests (114) and ESLint now pass:
npm test ✔️
npm run lint ✔️
Updated the position of the cursor on the user input box to be at the
end of the text when the user uses the arrow keys to navigate through
the input history in order to better match the behavior of a terminal.
