fix(cli): widen Windows .bat wrapper fix to custom-name alias path

The profile alias --name path in main.py rewrote the wrapper with a
hardcoded #!/bin/sh script right after create_wrapper_script(), clobbering
the .bat on Windows and reintroducing the exact bug for custom aliases.

create_wrapper_script() now takes an optional target so the alias file is
named after the alias while the -p content references the profile — one
platform-aware code path, no post-hoc rewrite.
