HopOS v1.3.0 — sharegroups

Cooperative core sharing, strictly opt-in. A sharegroup packs apps you explicitly name onto a shared pool of whole cores: members hand the core over when idle (explicit yield — no timer, no preemption), each still inside its own stage-2 cage with its own network stack. Sharing never happens involuntarily — ungrouped apps keep the full whole-core guarantee. Small boards now fit more apps than cores.
