docs(audio-rooms): full moq-lite wire spec + IETF gap call-outs

Background research turned up the complete moq-lite (Lite-03) wire
format from kixelated/moq-rs and @moq/lite v0.1.7. Folded the spec
into nestsClient/plans/2026-04-26-moq-lite-gap.md as a phase-5
implementation plan:

  - ALPN ("moq-lite-03"); no SETUP/control message in Lite-03 (the WT
    handshake IS the handshake)
  - Per-request bidi streams keyed by ControlType varint (Announce=1,
    Subscribe=2, Fetch=3, Probe=4)
  - AnnouncePlease(prefix) / Announce(status, suffix, hops) shape
  - Subscribe with priority (raw u8), ordered, maxLatency (ms),
    startGroup/endGroup (off-by-one None-encoded), reply Ok/Drop
  - Group = uni stream with (DataType=0, subscribeId, sequence)
    header followed by varint-length frames until QUIC FIN
  - No datagrams; no per-frame envelope beyond size
  - Mandatory path normalisation; FIN-as-unsubscribe; RESET_STREAM
    for errors

Phase-5a..e implementation plan included (~1 week scope).

Doc + KDoc updates so the IETF MoQ-transport code is correctly
labelled and the moq-lite gap is discoverable from every entry point:

  - .claude/CLAUDE.md project description and architecture diagram
  - nestsClient/plans/2026-04-26-audio-rooms-completion.md status block
  - MoqSession.kt, MoqMessage.kt, MoqObject.kt, MoqCodec.kt KDoc — flag
    these as "IETF draft-ietf-moq-transport-17, NOT moq-lite", with
    pointers to the gap doc
  - NestsConnect.kt — note that step 3 of the listener handshake
    (SETUP) does NOT match nostrnests's relay framing
