Add watch keys to switch the inner target - #14
Merged

Conversation
While watching, `j` reruns on JavaScript, `l` on Erlang and `k` toggles
between the two. The watcher already passed `--target` to every inner
run explicitly and read nothing target-specific back, so the target
becomes loop state: `inner_args` is split into `parse_watch_args` and
`build_inner` (and kept as their composition for the existing tests),
and `wait_for_change` returns the target the next cycle should use. The
run banner names the target and the status line lists the keys.
On the JavaScript host the keys are single keypresses through the
existing key worker (commands 4/5/6). The Erlang host gains a real key
channel for them: the line-based quit listener now knows the watcher's
pid and posts `{vouch_watch_key, N}` for `j`/`l`/`k` + Enter, which
`take_pending_key/0` drains with a zero-timeout receive, so on the BEAM
they work like `q` + Enter does.
