Vyomi v2.8.0

VPC — the last data plane. Closes PARITY P4 #15 completely: the first real
network simulation, and the final open parity data plane. Lands in the shared cores,
so Nano gets it too.

Added

• VPC core (core/vpc_core.py):
  • Model: VPCs, subnets, stateful security groups, route tables + routes,
    internet gateways, stateless network ACLs.
  • Control plane (native EC2 Query protocol → XML): CreateVpc, CreateSubnet,
    CreateSecurityGroup, AuthorizeSecurityGroup{Ingress,Egress}, CreateInternetGateway
    / AttachInternetGateway, CreateRoute, CreateNetworkAcl / …Entry / Associate,
    DescribeVpcs.
  • Data plane — reachability analyzer (analyze_reachability): given a source +
    destination + port it evaluates the full path — route table (longest-prefix
    match) → security groups (stateful; default-deny ingress) → network ACLs
    (stateless; first-match) — and returns reachable + the blocking reason + the
    evaluated path. No catalog stub can fake this; it requires real network semantics.
  • Wired into the router (EC2 Query: ec2 cred scope + Action-based); vendored to Nano.

Milestone

• The parity backlog is now fully closed. P0, P1, P2, P3 and P4 are all done;
  every parity data plane across AWS, GCP and Azure is covered. Remaining work is
  per-service depth, not missing subsystems (see docs/PARITY-GAPS.md §7).
