Module draft11 

MoQT client implementation for draft-11.

Each draft lives in its own top-level module with a complete, independent implementation: connection, endpoint state machine, event types, observer trait, and per-flow state machines (subscribe, fetch, announce, track status). No code is shared across drafts — each draft carries its own copy because wire-level differences would make a shared layer leaky.

Enable via the draft11 feature.

Differences from draft-10

Draft-11 is a structural change from draft-10. The most visible shifts:

• subscribe_id is renamed to request_id throughout the control plane.
• MAX_SUBSCRIBE_ID / SUBSCRIBES_BLOCKED become MAX_REQUEST_ID / REQUESTS_BLOCKED.
• Subscribe gains a forward field; group_order and filter_type are carried as VarInts rather than typed enums.
• SubscribeOk collapses the largest group/object pair into a single optional largest_location; SubscribeError gains a trailing track_alias; SubscribeDone gains stream_count.
• Announce / AnnounceOk / AnnounceError and SubscribeAnnounces* use request_id instead of carrying the namespace on every reply.
• TrackStatusRequest / TrackStatus are request-id keyed and TrackStatus no longer echoes the track namespace / name; it carries a largest_location.
• Fetch is restructured into a FetchPayload enum (Standalone vs Joining); FetchOk uses a single end_location and adds end_of_track.
• The data-stream layer adds subgroup variants 0x08–0x0D, datagram types 0x00–0x03, and per-object extension headers.
