game: implement SMSG_PET_SPELLS/MODE/BROKEN and pet action plumbing

Browse source 
SMSG_PET_SPELLS: Parse full packet — pet GUID, react/command state,
10 action bar slots, per-spell entries with autocast flags.  Previously
only read the GUID.

SMSG_PET_MODE: Parse petGuid + mode uint32 (command low byte, react
high byte) to keep stance state in sync after server updates.

SMSG_PET_BROKEN: Clear pet state and show "Your pet has died." chat
message.

SMSG_PET_LEARNED_SPELL / SMSG_PET_UNLEARNED_SPELL: Maintain pet spell
list incrementally.

SMSG_PET_CAST_FAILED: Parse and log cast count + spell + reason.

New state accessors: getPetActionSlot(), getPetCommand(), getPetReact(),
getPetSpells(), isPetSpellAutocast().

CMSG_PET_ACTION: Add targetGuid (uint64) field — the wire format
requires petGuid(8)+action(4)+targetGuid(8).  Was sending an 12-byte
packet instead of the required 20 bytes.

sendPetAction(): New method that builds and sends CMSG_PET_ACTION with
the correct target guid.
