Fixes#34, #35, #36
- all_hints: add Foundation as source for Tableau hints (guarded by
take_from_foundation); previously H key never suggested Foundation→Tableau
- end_drag / touch_end_drag: enforce take_from_foundation at input layer
so a rejected-by-core MoveRequestEvent is never fired
- animation_plugin: pub CARD_ANIM_Z_LIFT so card_plugin can consume it
- update_card_entity: set CardAnim start.z = z + CARD_ANIM_Z_LIFT to
eliminate 1-frame z artifact where animated card appeared behind resting cards
- solitaire_app: use AutoVsync on Android (caps GPU at display Hz vs
spinning at 200+ fps); add WinitSettings unfocused reactive_low_power
so app draws ~1fps when backgrounded
