* fix(desktop): stop running app locking win-unpacked before pack
On Windows a running Hermes.exe keeps an exclusive lock on
release/win-unpacked/Hermes.exe, so electron-builder's pack cannot
replace it and dies with "remove ...\Hermes.exe: Access is denied" /
ERR_ELECTRON_BUILDER_CANNOT_EXECUTE (before-pack hits the same EPERM
cleaning the dir, and the cache-purge retry repeats the failure since
the lock is still held).
Before building the packaged app, terminate any process whose
executable lives inside this build's release/ tree so the rebuild --
including the installer's headless --update rebuild -- can replace the
binary. Scope is narrow (only exes under release/), POSIX is a no-op
(it can unlink a running binary), and the final error now points
Windows users at the running-app cause.
* test(desktop): cover the win-unpacked lock-breaker helper
Verify _stop_desktop_processes_locking_build is a no-op off-Windows,
terminates only processes whose exe lives under release/ (sparing our
own PID and unrelated installs), and short-circuits when no release dir
exists.
