refactor(battle-node): move handshake phase reads to per-participant

Browse Source 
ComputeFrames now reads (from as IHasHandshakePhase)?.Phase for the
four handshake arms (InitNetwork, InitBattle, Loaded, Swap) and the
TurnEnd gate, transitioning the participant's Phase instead of the
session's. RealParticipant implements IHasHandshakePhase via the new
Phase property; the session-level BattleSession.Phase stays for the
Terminal short-circuit.

Scripted dispatch + wire shape unchanged (single-Real-participant case
collapses to Phase 1 semantics). Test fixture migrates FakeParticipant
to FakeRealParticipant for the side that drives handshake states. The
bot's TurnEnd previously rode the session-level AfterReady arm; with
that arm now gated on the sender's per-participant Phase (which the
bot lacks), TurnEnd joins TurnStart/Judge in the scripted-bot
forwarder arm so the v1.2 burst still reaches the real participant.
