Missing notification/error when GHDL Plugin is not installed #24
Description
Currently, OneWareStudio does not provide any feedback (error message or notification) if the GHDL plugin is required for an action but is not installed or enabled. This can lead to confusion when simulation-related features fail silently or simply do not appear as expected.
Expected Behavior
If a user tries to perform an action that requires the GHDL plugin (e.g., running a simulation) and the plugin is not found, OWS should display a clear error message or notification.
This message should:
Inform the user that the GHDL Plugin is required for this action.
Ideally, guide the user on how to install or enable the plugin.
Actual Behavior
No error message or notification is shown. Features that depend on the GHDL plugin either fail silently or are unavailable without any explanation, leaving the user unaware of the missing dependency.
