fix: ADD_SWITCHER keyword syntax - special handling for 'as' keyword format

The ADD_SWITCHER keyword was generating comma-separated params (ADD_SWITCHER(id, label))
instead of the expected Rhai custom syntax (ADD_SWITCHER id as label).

This fix adds special handling in the multiword processor to output the correct
format when processing ADD_SWITCHER with 2 parameters.

Fixes #495
