Reposition sandbox messaging from ephemeral to persistent-first

beran-t · beran-t · commit ff59ade8812c · 2026-03-02T11:43:55.000+01:00
Replace ephemeral language (spin up, disposable, destroyed automatically,
alive for 5 minutes) across 15 doc pages with persistent-first framing.
Sandboxes are now described as long-running by default with auto-pause,
while preserving isolation, security, and scalability messaging.
