feat(app): GameWindow wires Chat/Combat/Spellbook/Items into session

Exposes Core state classes as public fields on GameWindow so plugins +
UI panels can bind directly, then calls GameEventWiring.WireAll inside
live-session setup to connect the parsed GameEvent stream to them.
HearSpeech (standalone GameMessage, not 0xF7B0-wrapped) is routed via
a separate lambda since it has its own dispatch branch.

After this commit, every server-sent event that the Phase F.1 / E.4 /
E.5 / H.1 parsers handle actually mutates client state live:

- Chat: ChannelBroadcast, Tell, TransientMessage, Popup, HearSpeech
- Combat: UpdateHealth, Victim/Defender/Attacker/Evasion notifications,
  AttackDone
- Spellbook: MagicUpdateSpell, MagicRemoveSpell, enchantment
  add/remove/dispel/purge
- Items: WieldObject, InventoryPutObjInContainer

WorldTime + Lighting added as public-field Core services so the
renderer and plugin API can read "current day fraction" / "active
lights" directly.

Build green, 602 tests still pass.
