Added polyfills for `Map.getOrInsert()` and `Map.getOrInsertComputed()` from the TC39 upsert proposal and refactor the codebase to use them. These methods replace the common "check if key exists, then set default" pattern with a single atomic operation. This improves code readability and eliminates redundant map lookups throughout the player. --------- Co-authored-by: Álvaro Velad Galván <ladvan91@hotmail.com>
