* Hand browser and web app launches to the running browser directly

With a Chromium-based browser already running, each launch started a second
browser process only to pass its command line over the profile's singleton
socket and exit, ~165ms before the running browser even heard of it.
omarchy-cmd-browser-handoff sends that message itself with socat and waits
for the ACK, so a web app opens in ~210ms instead of ~430ms.

It hands off only what it can do exactly as the browser would: the packaged
browser binary rather than a wrapper, a flags file holding nothing beyond the
process flags Omarchy ships, no other data directory, and a socket we own.
Anything else, or no answer, launches the browser as before.

* Hand Brave Origin launches to the running browser too

/usr/bin/brave-origin is the package's own launcher, reading
brave-origin-flags.conf, with the profile in BraveSoftware/Brave-Origin.
A web app now opens in ~158ms instead of ~345ms.
