the raid tab lands, and sounds take the reference's voice buses

- the social window's fourth tab, Raid: the eight-subgroup grid over the roster, drag a member between subgroups, Convert To Raid, promote / demote assistant, uninvite, Ready Check with its popup, and the Raid Info flyout on the new `CMSG_REQUEST_RAID_INFO` / `SMSG_RAID_INSTANCE_INFO` wire (byte-golden against vmangos, an empty answer decoding as an empty list); `raid1`..`raid40` unit tokens, and `/partytest raid` stages a roster for a solo look
- an imbue pressed with an empty weapon hand says "Your weapon hand is empty" instead of raising a cursor — the attribute bit has two readers in the reference and the second is the error (corrects the day's first cut)
- sounds route onto the reference's own voice buses with its per-bus caps (the 0x87ce60 table, pinned as bytes): weapon impacts and clangs share four voices, footsteps six, the attacker's grunt one, the victim's injury two — so a pack swinging together makes about a dozen voices where it made dozens
