`RAID_ROSTER_UPDATE` fired only when a member's guid, rank, subgroup or online bit moved. A raid list that changed only a death, or an identical re-send, fired nothing, so the raid pullouts and addons listening on it went stale.
After each raid `SMSG_GROUP_LIST` rebuild, the reference's raid roster writer `0x4ba5f0` signals `RAID_ROSTER_UPDATE` whenever no member name is pending (`0x4babdf`-`0x4babef`). A list without the raid flag signals only when it drops a held raid (`0x4ba57b`).
`GroupState` now counts these per list, and the feed fires one event per list since its last look, as #691 does for `PARTY_MEMBERS_CHANGED`. The key compare stays as the edge for world entry, which fills our own row.
Test: with the default UI and `Blizzard_RaidUI` loaded, a death-only raid list turns the pullout row red.
Fixes#690
