Copy a scalar from source to destination

Usage

copy_scalar(
  destination,
  source,
  name,
  rename = NULL,
  default,
  overwrite = FALSE,
  type = NULL,
  insist = TRUE
)

destination: A Daf object to copy to
source: A Daf object to copy from
name: Name of the scalar to copy
rename: Optional new name for the scalar in the destination
default: Default value if scalar doesn't exist. If not provided (the default), an error will be raised if the scalar is missing in the source. If explicitly set to NULL, the copy will silently skip missing scalars.
overwrite: Whether to overwrite if scalar already exists
type: Optional type to convert the scalar to (e.g., "Float64", "Int32"). If NULL, the original type is preserved.
insist: Whether to skip if the destination already has the scalar (FALSE) or to attempt the copy regardless (TRUE, the default). Only relevant when overwrite=FALSE.

The destination Daf object (invisibly)
