Return player alias from OnIdentified event

[tudddorrr]

OnIdentified event signature

• Changed PlayersAPI.OnIdentified from Action<Player> to Action<PlayerAlias>, so subscribers now receive the alias object directly instead of the full player object

Identify method return types

• Identify, IdentifySteam, IdentifyGooglePlayGames, IdentifyGameCenter, and HandleIdentifySuccess all return Task<PlayerAlias> instead of Task<Player>, eliminating the need for consumers to access Talo.CurrentPlayer after calling these methods

Dead code elimination

• Removed redundant return Talo.CurrentPlayer lines from IdentifySteam, IdentifyGooglePlayGames, and IdentifyGameCenter since the underlying Identify() call now returns the alias directly, making the API surface more consistent and predictable
