fix(waybar): bar pokes missed the wrapped process — switches never touched the bar

nixpkgs wraps waybar, so the running comm is `.waybar-wrapped`:
`pkill -x waybar` (state-sync restart/SIGUSR2 branches, tz-watch,
updates) matched nothing — a theme switch neither restarted nor reloaded
the bar, which then kept the gtk.css of whatever theme it started under
(the stale workspace-digit colors reported 2026-07-18; companion gtk fix
in the next commit). The unanchored pokes (recording, airplane,
theme-shot) had the opposite bug: `waybar` substring-matches the
supervisor's `nomarchy-waybar` comm too, and an unhandled RTMIN
terminates its bash — the pokes were killing the crash guard. All seven
sites now use `pkill … -x 'waybar|\.waybar-wrapped'`.
state-sync 0.5.1 → 0.5.2.

Verified live on Newton (V3-grade): new pattern restarts the bar under
the supervisor (fresh pid, supervisor alive); RTMIN+10 poke reaches the
bar, supervisor survives. V0 `nix flake check --no-build` + py_compile;
V1 HM generation + system toplevel build.
