Xubin Ren 28e0a76b80 fix: path_append must not clobber login shell PATH
Seeding PATH in the env before bash -l caused /etc/profile
to skip its default PATH setup, breaking standard commands.
Move path_append to an inline export so the login shell
establishes a proper base PATH first.

Add regression test: ls still works when path_append is set.
