Fix pirate battle UI cleanup and water tiling

[querielo]

MERGE THIS PR ONLY AFTER Stem-Studio/Engine#34

Summary

• clean up Pirate Ship Battle Royal overlay/countdown resources when the GameManager behavior is disposed
• clear transient scene objects created during play so restart/destroy paths do not leave cannonballs, VFX, or wake meshes behind
• set the OceanSurface texture

Screen.Recording.2026-06-03.at.16.57.05.mp4

Changes

• added GameManager cleanup helpers for:
  • countdown timers
  • overlay/countdown DOM nodes
  • transient scene objects stored in _cannonballs, _cannonVFX, and _wake
  • scene userData hooks like _skipToNextMatch
  • cached scene/window references
• reused the transient-object cleanup during restart so restart and dispose follow the same cleanup path
• updated the Pirate Ship Battle Royal stemscript material for OceanSurface to use tileAmountX=20 tileAmountY=20

Validation

• parsed GameManager.yaml, extracted embedded script, and ran node --check on the generated JS
• verified the stemscript material line includes tileAmountX=20 tileAmountY=20
