Verify plugin behavior for v1.0.0 release

[dasupradyumna]

Summary

All features slated for v1.0.0 release have been implemented now, and before the official release, the plugin needs to be tested and verified to check if there are any uncaught bugs and if all features behave as expected.

Cursorline in the Launcher is turned off when performing undo or redo actions.

[dasupradyumna]

All callbacks in edit mode registered to confirmation or accepting a choice mess up the cursorline.

Attempting to view an active task from the list hangs neovim - a mutex is probably being locked twice without being released.

[dasupradyumna]

Disable calling :LaunchConfig when the launcher is already open.

[dasupradyumna]

Triggering Undo or Redo event crashes neovim when entering edit mode via Add or Copy events. But entering edit mode via Edit event does not cause this bug ; probably related to a new config being added to the runtime list.
