feat: add raid roster info, threat colors, and unit watch for raid frames

Browse source 
GetRaidRosterInfo(index) returns name, rank, subgroup, level, class,
fileName, zone, online, isDead, role, isML — the core function raid
frame addons (Grid, Healbot, VuhDo) use to populate unit frame data.
Resolves class from UNIT_FIELD_BYTES_0 when entity is available.

GetThreatStatusColor(status) returns RGB for threat indicator coloring
(gray/yellow/orange/red). Used by unit frames and threat meters.

GetReadyCheckStatus(unit) stub returns nil (no check in progress).
RegisterUnitWatch/UnregisterUnitWatch stubs for secure frame compat.
