This stores a constantly updated list of known HWNDs at
~/komorebi.hwnd.json which can be used to restore windows that may
disappear into a permanently hidden state during development using a new
'restore-windows' command with komorebic.
Added a query command to komorebic to return the WindowManager struct
serialized to JSON to help with debugging and maybe help others to build
tools like stackline for yabai in the future.
Allow the number of workspaces for a given monitor to be pre-created, so
that configuration options can be sent (name, padding, layout) before
the workspace has ever been activated.
