Nushell `--include` only includes for `--command` and not for scritps

Describe the bug

Executing nu -I does not include the path to the lib dirs when executing a nu script but only if a command is executed.,

How to reproduce

Run the following nushell script:

print "Creating module in /tmp/sub_dir"
mkdir /tmp/sub_dir/my_module
"export def foo [] {print 'hello!'}" | save -f /tmp/sub_dir/my_module/mod.nu

# execute sub-shell
print "Including module in subshell as a command:"
^nu -I "/tmp/sub_dir" -n -c "use my_module *; foo"
print "Command works!"

print "Storing command as a script"
"use my_module *; foo" | save -f /tmp/script.nu

print "Executing from a script:"
print "will fail"
^nu -I "/tmp/sub_dir" -n /tmp/script.nu

Expected behavior

Given the documentation:

-I, --include-path <String> - set the NU_LIB_DIRS for the given script (delimited by char record_sep (''))

I would expect it to work for both scripts and single commands.

Configuration

Additional context

I, as a rust n00b not knowing the code-base, can't really see anything obvious that might indicate the behavior:

Happy to provide additional information/help if possible!

Start with the reproduction script and inspect src/main.rs around lines 204-213, where the issue links to command-line handling. Run the shown -I examples to confirm the difference between -c and script execution. Done means the include path works consistently for both commands and scripts.
