Host-only 10.99.0.0/24 bridge with no uplink/NAT; firewall drops VM
traffic leaving the bridge so unikernel VMs can reach only the gateway
(mc-proxy). Implements Phase 2 mandatory-mediation networking.

Override the shared mcp.nix sandbox (PrivateDevices) on straylight so the
MCP agent can boot Nanos unikernel VMs under QEMU/KVM and manage TAP
devices for isolated networking.

Add configs/mcp.nix (mcp user UID 850 + mcp-agent service) and open
firewall ports for DNS/mc-proxy/agent/master as straylight takes over
the master + MCIAS + MCNS core role from rift.

BIOS boot with GRUB on /dev/xvda, MCP agent via systemd,

The LUKS device is named "luks-5c5e94fc-..." in hardware-configuration.nix
which already has the FIDO2 options. The "crypted" reference caused a build
error. Also fix duplicate attribute definitions and unnecessary config wrapper.

New root CA cert issued during Metacrypt vault rebuild. Same key

Same key, added CRL Sign to key usage extensions. Distributed to
all nodes and NixOS system trust store.

- Use nixpkgs.hostPlatform module instead of deprecated system arg to lib.nixosSystem
- Rename services.logind.powerKey to services.logind.settings.Login.HandlePowerKey

Rootless podman deeply caches the UID in storage, subuid mappings,
and systemd sessions. Changing it destroys all container state.

All nodes now list 1.1.1.1 and 8.8.8.8 as fallback nameservers after
MCNS. When MCNS is down, internal names (.svc.mcp.metacircular.net)
fail but external DNS (google.com, github.com, etc.) keeps working.
Lesson from 2026-04-03 incident: without fallbacks, MCNS failure
caused total DNS blackout including external services, forcing
Tailscale to be disabled to restore any DNS resolution.

UID 995 conflicted with sshd on orion. Pin to 850 (the 800-899 range
is unused on all nodes and well below NixOS auto-assign range).
Pin GID to 850 as well for consistency.
