Merge pull request 'fix(kugetsu): destroy --base and --pm-agent actually delete opencode sessions' (#113) from fix/destroy-removes-opencode-session into main

Previously destroy only removed local session files but didn't delete
the sessions from opencode's database. This caused init to reuse the
same session with old context.

Now destroy calls 'opencode session delete <id>' to properly remove
the session from opencode.
