run0: Give --empower its own color, title and emoji

When in --empower mode, all created files will be owned by the current
user, which could be problematic when creating files outside of the
current user's home directory, as other processes running as the same
user would be able to edit those files.

While this is a bit of an edge case since users already have to go through
the effort of writing --empower to indicate they want a privileged session
as the current user, it's not unphatomable to think they could start an
empowered session which they later return to and continue using. Currently,
it's not easy to differentiate a regular run0 session and an empowered session
at a glance, so users might think they're using a regular run0 session when
they're actually using an empowered session.

To address this problem, let's give empowered session their own identify, by
making the background orange, using the pumpkin emoji as the shell prompt
prefix and giving them an orange circle as the PTY title.
