Three one-shot console.info calls so the Phase 3 milestone-B parity
check is unambiguous from the browser console alone:
- [wall:registry] system bundle mounted — fires when RegisteredSystems
lazy-loads nodes/src/wall/system.tsx (exactly once per viewer mount
when the flag is on).
- [wall:registry] first WallRenderer mounted — fires once when the
first registry-driven WallRenderer mounts.
- [wall:legacy] first legacy WallRenderer mounted — fires once if the
legacy path is active (flag off, or kind not registered).
Module-level booleans gate the renderer logs so they don't spam in
scenes with many walls. Drop all three alongside the feature flag at
Phase 3 sign-off.
