* feat: acquire requested video layer directly at HIGH quality by default Two changes that together remove the visible low->high quality ramp for a new subscriber (both publisher-first and subscriber-first join orders): 1. Default a subscriber's initial video quality to HIGH on bind instead of LOW for adaptive stream, so the subscribed max layer is the top layer. Adaptive stream clients can still scale down afterwards based on viewport. 2. On initial layer acquisition the forwarder/selector latch directly onto the allocator's target (the requested top layer) instead of opportunistically latching onto the first lower key frame that arrives. A short initial-acquisition grace aims the target at the requested layer; if it does not show up in time, the target falls back to the highest layer seen so acquisition never stalls. Always on - no configuration flag.

Plumbed from config.RTC.EnableStartAtDesiredQuality through ParticipantParams -> SubscribedTrack/DownTrack -> Forwarder -> simulcast selector, gating all three behavior changes: the HIGH default on bind, the forwarder's initial-acquisition grace, and the selector's direct-latch-onto-target.
