Main gained wai-quantum 0.6.4 and other merges; the only conflict was the CHANGELOG's top insertion, and no other file is changed on both sides. Co-Authored-By: Claude Opus 5.5 <[email protected]>

joule-moq-relay: the metering test states what the record says of a closing session
As a session closes the relay ends its subscriptions one at a time, so a moment after its last media subscription ended and before its receipts or events ones did is time on no media track, class 8. Under load this happened in 1 of 64 runs (76 us, 2.3 ms into the close) and failed the test's assumption that there is none. The test now requires no time above layer 0 and class-8 time only within a session's close, and reports each session's spans on failure; the README says how a closing session is classed.

wai: the relay's metering record re-recorded with the final room_metering test
Co-Authored-By: Claude Opus 5.5 <[email protected]>
joule-moq-relay: the metering test reads concurrently and ends its subscribers first
The subscribers read their streams concurrently with the base's collect_concurrent, the slow one only after the load has arrived, as slow_subscriber.rs now does. Their sessions end before the publishers', so no subscription ends while the subscriber still holds another and the layer classes are what the test states.

joule-moq-relay: the per-hop session record of a WAI room
The relay signs WAI's per-hop session record (WMH1, wai/extensions/live-metering.md section 3) of a room from its session summaries: per track and direction the objects and bytes, the drops by reason with the receipts forwarded, its subscriber sessions' time by layer class, the events delivered, and a ledger of the room grants its sessions ran under, by the token each presented in SETUP. Its own energy is the unmetered marker. Nothing in the record is per object or per viewer. The session summary (format /2) keeps what the record is made from: per-track publisher counts, fetched bytes, objects queued at the end and objects past Object ID 0 per track, layer spans per room, and the room grant. tests/room_metering.rs: two publishers, three subscribers, one slow; the record verifies and recomputes from the summaries. No new dependency. Co-Authored-By: Claude Opus 5.5 <[email protected]>
