This PR

• is a bug fix

Describe the changes below:

Game#setUpRenderer added contextLost.bind(this) and contextRestored.bind(this) to the canvas without storing references to them, so Game#destroy can't remove them.

If a destroyed game's context was lost later (like if the browser evicts it for too many active contexts), then contextLost would throw Cannot set properties of null (setting 'contextLost'). The bound handlers are now kept on the game and removed in destroy().

[Copilot]

🟢 Approval recommended

Both listeners are removed using their original references before renderer teardown, with no unresolved issues.

No open issues 🎉
