feat(battle-engine-port): M7 COMPLETE — targeted destroy resolves headless (follower death / board-removal)

Browse Source 
First proof that follower DEATH / board-removal commits in the authoritative
part of PlayCard headless (not the cosmetic post-Process tail). Card 800144120
(cost-0 when_play destroy of a select_count=1 enemy follower) resolves via the
M6 selectedCards path: selected enemy follower removed (board -1 + cemetery +1),
un-selected untouched (routing confirmed load-bearing by swapping the selection).

Shim gap fixed (the predicted M7 cost): SkillProcessor.SelectCardToHaveDestroyVoicePlay's
cosmetic death-voice tail NRE'd on three M1 default!/Null* shadows
(IBattleCardView.VoiceInfo, CardVoiceInfoCache.GetCardVoiceInfoForBattle,
ReadOnlyVoiceInfo.GetDestroyVoice — the last unusable as the interface since
m1_stub_gen dropped its : IReadOnlyVoiceInfo base). Fix = one hand shim
HeadlessVoiceInfo : IReadOnlyVoiceInfo returning the engine's own
VoiceAndWaitTime._nullVoice sentinel, wired into the two generated seams with
// HEADLESS-FIX markers. No Engine/ edit (drift clean).

dotnet test SVSim.BattleEngine.Tests -> 7/7 green; check_drift.py clean; engine 0 Error(s).

// M7 (the first card to prove follower DEATH / board-removal): a when_play TARGETED-DESTROY spell

// that REMOVES a card from the board. M2-M6 only ever ADDED to / mutated stats of cards already in
// play; none proved the engine commits board REMOVAL inside the authoritative part of PlayCard
// (rather than the cosmetic post-Process tail the prior docs flag). The new oracle dimension is
// BOARD REMOVAL: with TWO followers on the enemy board and ONE passed as `selectedCards`, the
// `destroy` must remove exactly the SELECTED follower (enemy board count -1, selected gone, landed
// in the enemy CemeteryList) while leaving the un-selected follower on the board. The un-selected-
// survives assertion is load-bearing the same way M4's delta-vs-base and M6's differential were:
// it distinguishes "the destroy was routed to the selection" from "a blanket board wipe" — and is
// confirmed by the routing already proven in M6 (the effect follows the selectedCards entry).
