Security + upstream fixes

- Network core moves to a root-only folder; BroV talks to a narrow root helper (netctl.py) over a user-only socket; install script verifies the mihomo SHA256 and migrates keys (scripts/netcore)
- Hardened runtime, no get-task-allow; bypassPermissions removed from the chat; concealed clipboard items are not restored; DangerCheck knows core, LaunchAgents and hook paths; dropped-file copies expire after 7 days
- Ported from upstream Coucou: 1h crash fix (d05f22b), safe settings.json writes (918d30e), Escape/fold for pending approvals (6012900, 40e3ba8), auto-close delay + reopen (74984f2, ea244a7), full AskUserQuestion (52b1562)
