feat: add 6 more WoW API functions for Lua addons

Browse source 
- UnitRace(unitId) — returns race name ("Human", "Orc", etc.)
- UnitPowerType(unitId) — returns power type ID and name ("MANA", "RAGE", etc.)
- GetNumGroupMembers() — party/raid member count
- UnitGUID(unitId) — returns hex GUID string (0x format)
- UnitIsPlayer(unitId) — true if target is a player (not NPC)
- InCombatLockdown() — true if player is in combat

Total WoW API surface: 29 functions.
