v3.22.3

Fixed

• Internal one-shot sessions no longer clutter project surfaces — sessions spawned by Pneuma's own machinery (project onboarding, session tidy, evolution) showed up alongside the user's actual work: they padded the project panel's "Recent sessions" list, inflated the session count and mode breakdown on launcher project cards, and could even win a project card's quick-resume as the "most recent" session — dropping the user back into a finished tidy run instead of what they were making. Sessions of any mode whose manifest declares hidden: true are now stamped internal at scan time (manifest-driven — third-party hidden modes get the same treatment) and filtered out of all three surfaces. The sessions themselves stay on disk and remain resumable by id.
