Release v1.79.0-beta.3 candidate

Publish the three integrated S8 issues since beta.2. Synchronize all seven version sources, rebuild committed frontend assets, tighten ratchets to measured facts, and update release metadata for LED strips. Canonical documentation screenshots were reviewed from Linux CI and accepted in the preceding derived commit.

Local checks: build/typecheck, bundle policy, bundle budgets, monolith checks and release-contract tests passed. Native-Windows unit run passed 3517 tests; two GNU-bash tests and one TypeScript diagnostic-shape test remain Linux-only. Full exact-SHA Validate is mandatory before publication.
