fix(coding-agent): stopped blocked vibe reset loops

Disable reset-mode loops when vibe mode prevents the required session transition, so the prompt is not resubmitted into the unchanged session.

Added focused regression coverage for the blocked transition.

Fixes #6607

 ### Fixed
 
-- Fixed `/new`, `/drop`, `/fork`, and `/move` crashing or doing unnecessary work when invoked during vibe mode; interactive session transitions now show the existing exit-vibe warning and leave the session unchanged ([#6607](https://github.com/can1357/oh-my-pi/issues/6607)).
