Phase 0: Repository-Initialisierung nach Bauplan v1.2

- Struktur gemäß §8 (Eigentumsgrenzen), PLAN.md als normative Basis
- Pflichtdokumente: STATUS.md, ERRORS.md, TEST_REPORT.md, CHANGELOG.md, ADRs
- ADR-0001 Python 3.13-Pin, ADR-0002 GStreamer 1.28.6-Pin (Windows),
  ADR-0003 IPC TCP+MessagePack v1
- Kernpakete: hms_protocol, hms_domain, hms_parameter, hms_artnet,
  hms_adaptive, hms_capabilities, hms_plugin_sdk
- Renderer-Spike: D3D11-Primärpfad + Dev-GL-Pfad (§36 Nr. 4-5)
- Control Core: FastAPI REST + WebSocket (§36 Nr. 9)
- Beispielplugins: Passthrough + Gaussian Blur (3 Adaptive-Quality-
  Varianten, HLSL/GLSL/GLES)
- Tools: Art-Net-Emulator, Fixture-Generator (Master32/Layer64-CSV),
  Capability-Probe
- JSON-Schemas: IPC, Plugin, Projekt, Cluster
- 121 Unit-/Integrationstests grün, Ruff grün

Gate 0 bleibt offen: Hardwaremessungen nur auf echter Windows-Referenz-
hardware gültig (§29.7, §33).
