cl-tty.input:read-event has bugs (CSI parser timeout causes :escape
to be returned for arrow keys). Replace with direct read-raw-byte
calls that are proven to work for CSI sequences. The inline detection:
- Read first byte with 100ms timeout
- If ESC (27), read two more bytes with 150ms timeout each
- Map 65→:up, 66→:down, 67→:right, 68→:left, etc.
- Other bytes converted via the same cond chain as before
Also re-add resize check (was handled by read-event).
Use handler-case around the reader to prevent any reader errors
from crashing the TUI. Re-add Swank *error-output* redirect.
