Function get_basic_spells_from_play_effect 

pub fn get_basic_spells_from_play_effect(
    game: &GameState,
    tgt_card: CardId,
    controller: PlayerId,
) -> Vec<SpellAbility>

Collect the basic spell abilities that a Play$ effect could cast from tgt_card. Mirrors Java AbilityUtils.getBasicSpellsFromPlayEffect(Card, Player).

“Basic” means the non-alternative cost variants — the Rust engine has no Spell wrapper analogue yet, so we synthesize fresh SpellAbility objects from the target card’s ability text, filtering to spells / land abilities the way Java does in collectSpellsForPlayEffect.
