Reload.sh Orphans

[brendancohan]

Reloading quickshell, with the current setup at least, creates many orphaned processes from inotifywait, dbus-monitor, socat, etc. This is mostly happening it seems because many of the panels are calling these processes up with exec

command: ["bash", "-c", "while [ ! -f ~/.config/hypr/settings.json ]; do sleep 1; done; inotifywait -qq -e modify,close_write ~/.config/hypr/settings.json"]

adding in the exec command should resolve this for all the inotifywait processes, but I think there is some further cleanup required for the socket and pipe processes there may be a little more cleanup necessary.

I reproduced the watcher/process leak and found a concrete failure mode for the TopBar watcher subtree.

Old generations of *_wait.sh and/or their nmcli, pactl, dbus-monitor, socat, and udevadm children were being adopted by systemd --user. The network/audio scripts could remain blocked in an external foreground grep, while Bluetooth/keyboard used background pipelines that could leave grandchildren behind.

The proposed patch starts each watcher root and long-running monitor child with a parent-death signal, retains cleanup traps, and replaces the grep waits with Bash read loops.

I explicitly killed Quickshell after the patch and got:

• watcher roots: NONE
• Quickshell monitor children: NONE
• systemd-adopted watcher/monitor processes: NONE

Then I restarted Quickshell and got exactly one of each watcher again.

This addresses the watcher/socket/monitor part of #89; it does not claim to fix every separate inotifywait call in the repo.
