rootiest cc14f7fb3d fix(config-toggle): replace read -k 3 with read -k 1 + ESC sequence detection
fish's read -k N waits for exactly N bytes; single-char keys ('q', 'j',
Space, Tab) were blocking indefinitely waiting for 2 more bytes, causing
the input loop to appear unresponsive. Random 3-key bundles were then
processed as unrecognised input, triggering infinite redraws.

Switch to read -k 1 (one raw byte per call). Arrow keys still work: the
terminal sends ESC+[+A/B as a burst, so after reading ESC the two
continuation bytes are already in the TTY buffer and the follow-up reads
return immediately. Bare ESC now passes the next keypress through as the
effective key rather than exiting (q/Q remain the exit keys).
