Phase 0 lab plan: topology, VM management, experiments E1-E9

docs/PHASE0-PLAN.md:
- Lab topology mirroring production 1:1 - two minimum-shape sites
  (console + 2 cockpits) + hub, hub-and-spoke WireGuard over a
  host-only "WAN" net with netem as the simulated internet.
- Lab IP conventions (strawman seat map; flagged for alignment with
  real bay numbering before Phase 1).
- VM inventory: full 9-VM set and a 5-VM minimum-viable start.
- VM management recommendations: VMware Workstation Pro 17 (free
  personal; host is Win11 Home so no Hyper-V) for the first pass,
  Proxmox VE on a spare box as the persistent lab / future hub
  staging; gold images + linked clones, snapshot-per-experiment
  discipline, config-as-code under lab/, one-knob netem sweep script.
- Experiments E1-E9 with pass criteria mapped to the brainstorm's
  open questions: routed fabric + console RPC over WAN, broadcast
  locality, FS directed join + port matrix, latency cliff table,
  WAN-drop behavior, MTU, BT411 cross-subnet egg push, hub host +
  stream rehearsal, event-day dry run (SiteConfigMerge gate).
- Risks: MW4-in-VM rendering (physical-host fallback), vPOD fidelity
  limits, firewall discipline.
