input: external control channel via FIFO
Adds --fifo [path] opening a named pipe that accepts button commands from any
process. Supports momentary taps (a, start, name:N), deterministic hold/release
(+name / -name), and 'release'. Merges with keyboard input; held state carries
true key-up semantics the terminal can't provide. GBC_INPUT_DEBUG traces state.
