feat: parse SMSG_SPELLLOGEXECUTE CREATE_ITEM effects for profession crafting feedback

Browse source 
- Implement SMSG_SPELLLOGEXECUTE handler with expansion-aware caster GUID reading
  (packed_guid for WotLK/Classic, full uint64 for TBC)
- Parse effect type 24 (SPELL_EFFECT_CREATE_ITEM): show "You create <item> using
  <spell>." in chat when the player uses a profession or any create-item spell
- Look up item name via ensureItemInfo/getItemInfo and spell name via spellNameCache_
- Fall back to "You create: <item>." when the spell name is not cached
- Safely consume unknown effect types by stopping parse at first unrecognized effect
  to avoid packet misalignment on variable-length sub-records
- Adds visible crafting feedback complementary to SMSG_ITEM_PUSH_RESULT (which shows
  "Received:" for looted/obtained items) with a profession-specific "create" message
