Monsterbox 8.4.0 Gold

MonsterBox 8.4.0 — Gold Release

A gold stability release that consolidates a whole-application audit, complete in-app help coverage, a new whole-app health test, and a clean dependency-security bill of health.

No new frameworks, no new runtime dependencies, no API-contract changes. Everything below was verified in a hardware-less container: unit 168/0, system 339 passing (the one failure needs a real microphone), jaw 52/0 + head 21/0, all-pages browser health 24/24, npm audit 0 vulnerabilities, pre-deploy gate green.

Highlights

•	🛡️ Full 14-subsystem stability audit — 58 verified defects, all fixed (bar one intentionally-unchanged sync write).
•	🔧 Servo control restored — a committed null byte had been failing every PCA9685 servo move since v7.9.6.
•	💬 Complete mouseover/help coverage — every interactive control now has a tooltip, enforced by a reusable checker.
•	✅ New all-pages health test — 24 pages, every modal, zero errors.
•	🔒 Dependency security: 9 advisories → 0, no breaking changes.
•	🧹 Repo cleanup + documentation refresh for the release.

(The full body — security/crash/data-integrity/RPi detail, the tooltip and health-test sections, the dependency table, and the verification table — is in the attached file.)
