Plan: docs/superpowers/plans/2026-05-12-phase-c1.5a-portals.md. Four
tasks, TDD-style, each task is a single commit boundary:
1. EntityScriptActivator class + three xUnit tests
2. Wire into GpuWorldState (new optional ctor param + two ?. calls)
3. Construct in GameWindow with resolver lambda
4. Visual verification at Holtburg Town network portal + roadmap update
Spec amendments correct an inaccuracy in the 2026-05-12 commit
(06d7fbd): the activator's call sites live in GpuWorldState
(AppendLiveEntity / RemoveEntityByServerGuid), not directly in
GameWindow as the original spec described. Also fixes the test file
path: tests/AcDream.Core.Tests/... not AcDream.App.Tests/... per the
existing test-project convention. No design changes — same activator,
same trigger condition, same lifecycle ordering.
