[BOT] Implement Prowl, Stoic Strategist - #16656

Implements Prowl, Stoic Strategist // Prowl, Pursuit Vehicle (#9605), card-level only.

The attack trigger exiles the target into Prowl's linked exile zone and lets the card's owner play it through CardUtil.makeCardPlayable with Duration.Custom, so the permission ends once the card leaves exile. A small game watcher remembers which cards were exiled with each Prowl (keyed by its exile zone, not cleared between turns), and the "plays a card exiled with Prowl" trigger checks the played card's previous zone change against it. This covers both casting and playing a land, and works no matter which permission the player used. The back face reuses IfAbilityHasResolvedXTimesEffect with AbilityResolvedWatcher.

Tests cover an opponent's tapped creature cast by its owner (Prowl's controller can't cast it), a tapped noncreature Vehicle, a land creature played from exile, and the back face converting on the second resolution in a turn but not the first.
