test(battle-engine-port): M6 COMPLETE — targeted when_play damage spell resolves headless (selection-routing oracle)

Browse Source 
First card to exercise the selectedCards path of ActionProcessor.PlayCard
(dormant through M2-M5, all of which played selectedCards: null). Spell
800134020 (clan-1 cost-1, when_play damage=5 to a select_count=1 enemy
follower) resolves headless: with two vanilla followers on the enemy board
and one passed as selectedCards, the damage hits ONLY the selected follower
(13->8) and the un-selected one is untouched (7).

New oracle dimension: SELECTION ROUTING via a differential life-delta on two
surviving targets (selected -5, un-selected 0) — reads the authoritative
damage path M3 proved, with no dependence on follower death/board-removal
timing. Load-bearing confirmed (M4 discipline): swapping which follower is
selected makes the damage follow the selection (assertions fail for the right
reason), then reverted to green.

Like M4, a clean milestone: NO new engine/shim work — the selectedCards path
resolved on the existing shim surface. The only authoring was test-side: the
M6 card constants, a shared HeadlessEngineEnv.PutFollowerInPlay primitive
(create via the null-view seam + drive HandCardToField), and the oracle.

Engine still 0 errors; check_drift clean; dotnet test -> 6/6 green.
