feat(engine): shake/settle/deal animations (#54, #55, #69)

Browse Source 
Add FeedbackAnimPlugin with three card feedback animations:
- #54 ShakeAnim: horizontal shake on MoveRejectedEvent targeting
  destination pile cards; 0.3 s damped sine wave
- #55 SettleAnim: Y-scale bounce on valid placement (StateChangedEvent);
  1.0 → 0.92 → 1.0 over 0.15 s for all top-of-pile cards
- #69 Deal animation: slides each card from stock position to its deal
  position on NewGameRequestEvent (move_count == 0), using existing
  CardAnim with 0.04 s per-card stagger

Pure-function helpers shake_offset, settle_scale, and deal_stagger_delay
are public and covered by 6 unit tests. Fix pre-existing compile/clippy
errors: stubbed handle_confirm_input/handle_game_over_input, removed dead
CycleCardBack/CycleBackground variants, annotated ambient_handle field,
and fixed draw_mode.clone() in pause_plugin.
