docs(adr-115): v0.7.0 release notes + CHANGELOG refresh
## `docs/releases/v0.7.0-mqtt-matter.md` (new)
Full release-readiness document for the v0.7.0 cut. Sections:
- TL;DR — the architectural win in one paragraph
- What's new for end users (HA-DISCO + HA-FABRIC + HA-MIND + 8
blueprints + 3 Lovelace dashboards)
- What's new for operators (full CLI matrix)
- What's new for developers (feature flags, modules, test counts,
integration tests, benchmarks, validation harness, witness)
- Benchmark numbers (all ADR §3.7 targets beaten 1.6×–208×)
- Security (wire-boundary audit + 5 fuzz cases + --privacy-mode
architectural win)
- Reproducibility recipe (one block to verify the whole stack)
- Deferred-to-v0.7.1 (P8b rs-matter SDK wiring + P9b multi-controller
validation + CSA cert decision)
- Deferred-to-v0.8.0 (hard-fail plaintext + HACS-native integration)
- Acknowledgements (#776, #778, 17 commits, maintainer ACK)

3 blueprints — over-delivered)

- ESP32 validation harness + witness bundle
- Links to release notes + tracking issue + PR
