* feat(engine): tighten CharacterDesigner prompt to prevent look-alike characters
Expand the visualDescription rules into a 6-element mandatory checklist (hair
quad / eyes triad / face & build / outfit quad / personality-driven vibe /
silhouette tag) and add an explicit anti-collision rule comparing against the
existing cast across cross-color-family and cross-silhouette dimensions.
Also upgrade the user-message "已设定角色" block from soft hint to hard
constraint with an explicit pre-write scan step, nudging the LLM into chain-
of-thought differentiation before emitting tags.
All additions land in the session-stable system prefix, so prompt cache
absorbs the extra tokens — per-call billed token delta is ~0.

* fix(engine): replace pose examples with aura descriptors in personality vibe
The PERSONALITY-DRIVEN VIBE element listed concrete poses (arms crossed,
chin tilted up, slight slouch) which contradicted the earlier rule
banning transient poses from visualDescription. Switch to pure
atmosphere/aura keywords so the character card stays pose-neutral.
