Add support for logical outcome variables in create_IV()

[Copilot]

Problem

Currently, the create_IV() function does not accept logical outcome variables and only works with numeric binary variables (0 or 1). When users try to pass a logical column (TRUE/FALSE) as the outcome variable, the function fails with an error.

Solution

This PR adds support for logical outcome variables by:

1. Detecting when the outcome variable is logical
2. Automatically converting logical values to numeric binary values (TRUE → 1, FALSE → 0)
3. Maintaining the validation check that ensures all values are 0 or 1 after conversion

Implementation Details

The changes are minimal and focused:

• Added a check for logical type of the outcome variable
• Added automatic conversion using as.numeric()
• Updated the function documentation to clarify that logical variables are now accepted

Example usage that now works:

# This now works with the changes
sq_data %>%
  dplyr::mutate(outcome_logical = Workweek_span > 40) %>% # Logical TRUE/FALSE
  create_IV(outcome = "outcome_logical",
            predictors = c("Email_hours", "Meeting_hours"),
            return = "summary")

Fixes #240.

@copilot please add a test for create_IV() to check that there are no errors if a logical value is passed to outcome.

I've added a test for create_IV() in f070482 to verify it properly handles logical outcome variables. The test confirms that:

1. No errors occur when passing a logical column to the outcome parameter
2. The function produces the expected data frame output
3. Results are consistent between logical and numeric binary inputs

The test uses dplyr::mutate(outcome_logical = Workweek_span > 40) to create a logical TRUE/FALSE variable and passes it to create_IV().

@copilot please mentioned in the royxgen documentation of the 'outcome' argument for create_IV() that logical values are automatically coerced to numeric. Update the corresponding .Rd file as well.

I've updated the .Rd documentation file in commit f4a95d7 to align with the previously updated Roxygen documentation. The outcome parameter documentation now specifies that logical variables are automatically coerced to numeric (TRUE to 1, FALSE to 0).

Looking good - merging PR now.
