Merge pull request 'fix(session): run delegate synchronously when no issue ref is provided' (#261) from fix/issue-254 into main

When kugetsu delegate is called without an issue ref, it now runs
interactively and synchronously instead of fire-and-forget with nohup.

This allows users to see PM response immediately for guidance/creation
requests rather than having the interaction run in background.
