PR Review

This PR is clean. The changes are minimal and well-structured:

• leaderboards_api.gd: The inline return refactor is a valid simplification — no type safety concerns since Godot 4 typed array filter() preserves Array[TaloLeaderboardEntry].
• players_api.gd: identify_google_play_games correctly mirrors the single-arg pattern of identify_steam, includes a doc comment, and uses await appropriately.
• Version bump and README update are consistent with the rest of the codebase.

No improvements needed.
