fix(cthulhu): align altar, ritual, madness, star-spawn with wiki faq

[deathcats4]

Summary

• Aligns Altar to Cthulhu POD with "once per turn" restriction while keeping original altar behavior unchanged.
• Updates Complete the Ritual to place minions, attached actions, and base actions on the bottom of their owners' decks, matching POD wording.
• Reworks Madness Unleashed so discarded Madness cards go to the discard pile and each discarded card grants an optional draw+extra action, as per FAQ.
• Changes Star-Spawn of Cthulhu to move the specific Madness card from your hand into another player's hand instead of returning it to the Madness deck.

Details

• Altar to Cthulhu (POD): uses a per-turn UID tracker (turnUsedOngoingUids) in SmashUpCore, cleared on TURN_STARTED, so each POD altar only grants one extra action per turn, while the original altar still triggers every time you play a minion there.
• Complete the Ritual: now also places attached actions on minions onto the bottom of their owners' decks before clearing and replacing the base, so all cards here (minions + attached actions + base actions) are placed as per POD errata.
• Madness Unleashed: first discards the selected Madness cards to the player's discard pile via CARDS_DISCARDED, then asks how many times (0..N) to use the "draw 1 + extra action" option; it draws up to that many cards and grants the same number of extra action plays, matching the FAQ's per-card "you may" behavior.
• Star-Spawn of Cthulhu: directly transfers the chosen Madness instance from the acting player's hand into the target player's hand, aligning with "place a Madness card from your hand into another player's hand" instead of returning to the Madness deck and drawing a new one.

Testing

• npm run test:smashup (Smash Up test suite) passes with these changes; the only known failing test is the Innsmouth Locals deck-order expectation, which was already changed earlier to match the Locals FAQ and is being tracked separately.
