LANTERN purge B3+B5: delete the cycle/core/win-lose spine + onboarding; save epoch v7

Deletes CyclePhaseSystem, GoalReachedSystem, CoreDamage/CoreRestore, ThreatDirector,
CoreIntegrity/GoalProgress/RunPhase/RunOutcome/ThreatState components,
CoreVisualFeedbackSystem, and the whole Client/Onboarding slice (+6 test files).

Keepers reworked: RunDirectorSystem (UpdateBefore attr + launch guard + goal/threat
bank removed; sole SaveRequest raiser now), CycleDirectorSpawnSystem (ledger/meta
host only), WaveSystem UNGATED (waves run wherever a WaveDirector is baked),
EnemyAISystem core-fallback stripped, AmbientAudioSystem reworked (bed + run cues;
no CycleState gate), MusicSystem RunInfo-only, HudSystem big trim (goal meter, core
bar, siege banner, terminal banner, outcome flash, onboarding hook all gone),
MetaShop/ClassPrep/AimReticle siege gates dropped, DebugOverlay/ops re-meant
(SpawnWave=force next wave, EndSiege=quiet arena; SetCalm/AdvanceGoal/SetHeat
retired, bytes reserved), TuningConfig Core knobs retired (ids 20-23 reserved),
StorageMath.DrainFraction deleted, HowToPlay copy rewritten.

Save epoch v7 (fresh epoch, operator-approved): SaveData drops goal/core/outcome +
conveyor/machine-IO fields; MinLoadableVersion=7; PendingSave/PendingStructure
trimmed; RollTerminalCampaignForward deleted; SaveStructureScan signature slimmed.

390 tests green; Play world-creation clean (player + waves live, no exceptions).
