Step 6 of multi-instancing migration. HeadlessEngineEnv.EnsureInitialized
is split into EnsureProcessGlobals (idempotent, process-once) +
SeedCharaIdsOnCurrentAmbient (per-test). New TestBattleScope IDisposable
sets up a fresh BattleAmbientContext per test. NonParallelizable removed
from converted classes; assembly-level Parallelizable(Fixtures) enabled.
SVSim.BattleEngine.Tests fully green under parallel test execution.

Fold SetupCardEvent into a shared HeadlessEngineEnv.CreateHeadlessHandCard primitive
(consolidating the duplicated M2/M3 helpers), then add the M4 oracle: card 103111050
(ELF cost-1 1/1, when_play powerup add_offense=1&add_life=1 to target=self). New oracle
dimension = the played card's OWN stat delta (1/1 -> 2/2). Gate play_count>2 seeded via
the public AddCurrentTrunPlayCount; proven load-bearing (without the seed the fanfare
gates out and Atk stays 1). No new shim/data gaps were needed — only harness seeding.
Engine still 0 errors; check_drift clean.

Card 900124030 (ELF cost-3, when_play damage=3 to enemy leader) resolves to
correct authoritative state headless via the IsForecast/IsRecovery +
ActionProcessor.PlayCard path. New oracle dimension (opponent leader-life delta)
passes; 3/3 tests green; engine still 0 errors; check_drift clean.
Four headless gaps, each mechanical (no logic/Unity wall):
- Data seam: InitLeaderLife (SetupInitialGameState->InitializeClassLife subset);
leader BaseMaxLife was 0 => game-over => play silently rejected. M2 missed it
(only asserted leader life unchanged: 0==0).
- Runtime cast: re-attach IClassBattleCardView on the generated
NullClassBattleCardView stub (members already present; base-clause recovery
stripped the decl). Compiled fine -> M1 loop never surfaced it.
- M1 mis-cut: copy NullVfxWithLoading verbatim (its GetInstance() lazy singleton
was stubbed to default!/null). Same pattern as M2 NullCardVfxCreator.
- Card events: CreateHeadlessHandCard now calls SetupCardEvent so a spell's
OnPlay->RemoveSpellCardFromHand / OnFinishWhenPlaySkill->AddSpellCardToCemetery
fire (the bare CreateCardWithoutResources seam skips them).
