feat: add output power manager

FilesMonitor allows shell to monitor changes on a set of files.
This allows the shell to react in realtime any changes related
to its configurations such as: themes, keyboard, setting, etc.

 Wayland shell for diyac wayland compositor
+
+# Environment variables
+
+## Theme
+
+Default theme can be set using the envar `DIYA_DEFAULT_THEME`, this will cause the shell searching for CSS file theme in
+`/home/$USER/.themes/<name>/gtk-4.0/gtk.css`:
+
+* diya-shell: will looking for file: `dev.iohub.diya.session-shell.css`
+* diya-login-shell: will looking for file: `dev.iohub.diya.login-shell.css`
+
+# Virtual keyboard layout
+
+Default virtual keyboard keymap can be set via the `DIYA_VKB_KEYMAP` environment variable. When created virtual keyboard,
+the shell will search for keymap file in: `/home/$USER/.config/diya/xkb/${DIYA_VKB_KEYMAP}.keymap`
+
+
+# Launch terminal based application
+
+create file in `/home/$USER/bin/xdg-terminal-exec` with:
+
+```sh
+#! /bin/sh
+foot $@
+```
+
+this allows gtk4-launch to launch a terminal based application

+  <description summary="Control power management modes of outputs">
+    This protocol allows clients to control power management modes
+    of outputs that are currently part of the compositor space. The
+    intent is to allow special clients like desktop shells to power
+    down outputs when the system is idle.
+
+    To modify outputs not currently part of the compositor space see
+    wlr-output-management.
+
+    Warning! The protocol described in this file is experimental and
+    backward incompatible changes may be made. Backward compatible changes
+    may be added together with the corresponding interface version bump.
+    Backward incompatible changes are done by bumping the version number in
+    the protocol and interface names and resetting the interface version.
+    Once the protocol is to be declared stable, the 'z' prefix and the
+    version number in the protocol and interface names are removed and the
+    interface version number is reset.
