Replace the three-layer process management (trap cleanup, PPID-polling
watchdog subshell, /proc-scanning reaper) with kernel-level lifetime
binding: each wl-paste watcher is spawned under setpriv --pdeathsig TERM,
so it dies with the shell no matter how the shell exits.
- Delete watch.sh: the shell now spawns both watchers directly as
declarative Process commands instead of a wrapper script with traps
and a 1s polling loop
- Delete init.sh: reaping stale watchers from a crashed pre-pdeathsig
shell is a single pkill at startup
- Collapse capture.sh's dual stream/snapshot modes: wl-paste forwards
arguments to its watch command, so the mime rides along as $1 instead
of an env var, letting both modes share one emit_image function
- Turn the six-branch image mime chain into a loop
Net: two fewer files, three fewer runtime processes, and the watch-mode
capture tests now exercise the same argument protocol the shell uses.
