Merge pull request 'fix(kugetsu): warn if init run from non-empty directory' (#112) from fix/init-directory-warning into main

Warn users if running kugetsu init from a directory with files or
git repository. This prevents project context from contaminating the
base session, which causes forked sessions to have unwanted context.
