Consolidate every outbound domain onto the single endpoint resolver so a
Lark-brand user reaches Lark hosts consistently. The skills index and app
registration previously pointed at Feishu regardless of the configured brand;
they now follow it, while the default Feishu brand is unchanged.
Version checks respect the user's configured npm registry instead of assuming
the public one, and a lint guard prevents outbound hosts from being hardcoded
outside the resolver again.
