rnd(M02): extract character presenters

Work-Package: M02-RND-CHARACTER-PRESENTATION-001

Agent: sindo-main-codex

Tests: presentation/input/movement/terrain/camera regressions; coordinate/streaming/docs/coordination gates; renderer dry-run 7/7

Fidelity: preserves current sandbox model/outfit and Stand/Idle/Run/Walk behavior; build-12340 parity remains unverified
