scenix v1.9.1 — XR, Audio, And Physics Bridges

Scenix v1.9.1 — Animato no_std Bridge Fix

Scenix 1.9.1 is a dependency patch release. It picks up
Animato 1.7.3, whose
facade now declares #![cfg_attr(not(feature = "std"), no_std)], closing
scenix issue #21:
enabling the animato feature with std disabled no longer forces the
standard library into the build, so bridged animation works on bare-metal
and other no_std targets. No public scenix API changes.

Highlights

• animato bridge dependency 1.7.2 → 1.7.3:
  • The Animato facade (animato) is now no_std-capable and forwards the
    facade's core-only, tween, spring, physics, and color feature
    combinations to bare metal. scenix-animato with the animato facade
    feature compiles for no_std-only targets.
  • Upstream timeline and path facade features remain std-gated in
    Animato itself (their dependency trees still enable animato-core/std)
    — pre-existing behavior, unchanged in this release.
• Verified bare metal: cargo check -p scenix-animato --no-default-features --target thumbv7m-none-eabi passes; the same check previously failed with
  E0463 and cannot find attribute derive errors once animato was
  enabled.
• crates.io note: published scenix 1.9.0 already resolved Animato
  ^1.7.2 → 1.7.3 (semver-compatible), so the fix reaches downstream
  users automatically. v1.9.1 makes the workspace pin explicit.
• Accurately updated XR_VERSION, AUDIO_VERSION, and
  PHYSICS_VERSION markers to 1.9.1, and refreshed the Animato version
  references in the README, ARCHITECTURE, animation concepts, and FAQ docs
  to the 1.7.3 bridge target.

Upgrade

Nothing to do: depend on scenix/scenix-animato as before. Cargo
resolution pulls Animato 1.7.3 for any scenix = "1.9" consumer.
