/**
|
|
* Tests for slash command argument parsing and substitution.
|
|
*
|
|
* Tests verify:
|
|
* - Argument parsing with quotes and special characters
|
|
* - Placeholder substitution ($1, $2, $@, $ARGUMENTS)
|
|
* - No recursive substitution of patterns in argument values
|
|
* - Edge cases and integration between parsing and substitution
