The engine is constructed per session, seated once from the master seed + both
shuffled decks (F-N-5), and fed each frame via ShadowIngest — all inside a
try/catch in ComputeFrames so a shadow failure can never break live dispatch
(ND1/ND6). Routes still come from the existing handlers: wire output is
byte-for-byte unchanged. FrameDispatchContext gains the Engine ref for N2+.
csproj: PrivateAssets=compile on the engine ref so its global-namespace type
surface (MessagePackSerializer, UserConfig, UserCard, ChallengeConfig, ...) does
not leak transitively into SVSim.EmulatedEntrypoint (which references BattleNode)
and collide with that project's own types; the runtime DLL still flows.
All 238 BattleNode unit tests pass; EmulatedEntrypoint builds clean.

Behavior-identical; 231 BattleNode tests green with ZERO test changes.
The 10 handler arms no longer switch on BattleType:
- 4 Bot arms gate on the new FrameDispatchContext.OpponentIsAckOnly
(Other is not IHasHandshakePhase) — the participant property the audit asked for.
- 6 relay arms drop the Type == Pvp guard; it was redundant with BothSidesAfterReady()
(only a two-real-player session has both handshake phases). Its doc now records that.
- FrameDispatchContext.Type removed (+ the Type = Type in BuildContext). BattleSession.Type
stays for the session-level drop cascade.
Zero test churn because the stubs already encode the split: FakeRealParticipant/ProbeParticipant
implement IHasHandshakePhase, the bot stub FakeParticipant doesn't, and NewBotSession uses it as
the opponent.

Behavior-preserving; 231 BattleNode tests green.
FrameDispatchContext.BothAfterReady() -> BothSidesAfterReady() (7 call sites). The
4 inline `SenderPhase == AfterReady` checks in TurnEndHandler/TurnEndFinalHandler now
read a new SenderIsAfterReady property. Both carry cross-referencing docs so the
Bot-arm (sender-only) vs PvP-arm (both-sides) distinction is explicit at the type.

One enum conflated two axes. Split:
- HandshakePhase (per participant): AwaitingInitNetwork..AfterReady. On
IHasHandshakePhase.Phase, FrameDispatchContext.SenderPhase, the handler gates.
- SessionLifecycle (per battle): Active | Terminal. On the renamed
BattleSessionState.Lifecycle (was SessionPhase, defaulting to a handshake value)
and BattleSession.Lifecycle (was Phase). Reads are only != Terminal, so the
Active default is behavior-identical.
OpponentTurn was dead (never assigned) -> dropped. BattleSessionPhase deleted; the
two axes can no longer be cross-assigned.

Remove the now-unused SVSim.BattleNode.Lifecycle using from
FrameDispatchContext (it was only needed for ScriptedLifecycle inside
the deleted IsScriptedBot helper) and reword the SenderPhase doc comment
so it no longer references the removed dispatch-test scripted-bot stub.

The IsScriptedBot(ctx.From) forwards in JudgeHandler/TurnStartHandler/TurnEndHandler
and the 'if Type==Scripted' raw-forward only ever fired for ScriptedBotParticipant
emissions; NoOpBot (Bot mode) never emits, so they are dead. Routing is now purely
PvP-vs-Bot. Drops the IsScriptedBot helper.
