Draft & Deck Building Phase

Objective

Implement the "Draft Phase" (Pack Passing) and "Deck Building Phase" (Pool + Lands) logic and UI, bridging the gap between Lobby and Game.

Backend - Draft Logic (src/server/managers/DraftManager.ts):
- Implemented DraftManager class.
- Handles pack distribution (3 packs per player).
- Implements pickCard logic with queue-based passing (Left-Right-Left).
- Manages pack rounds (Wait for everyone to finish Pack 1 before opening Pack 2).
- Transitions to deck_building status upon completion.
Server Integration (src/server/index.ts):
- Added handlers for start_draft and pick_card.
- Broadcasts draft_update events.
Frontend - Draft UI (src/client/src/modules/draft/DraftView.tsx):
- Displays active booster pack.
- Timer (visual only for now).
- Click-to-pick interaction.
- Preview of drafted pool.
Frontend - Deck Builder UI (src/client/src/modules/draft/DeckBuilderView.tsx):
- Split View: Card Pool vs. Current Deck.
- Drag/Click: Click card to move between pool and deck.
- Land Station: Add basic lands (Plains, Island, Swamp, Mountain, Forest) with unlimited supply.
- Submit: Sends deck to server (via player_ready - Note: Server integration for deck storage pending final game start logic).
Integration (GameRoom.tsx):
- Added routing based on room status: waiting -> drafting -> deck_building -> game.
- Added "Start Real Draft" button to lobby.

Drafting: Fully functional loop. Players pick cards, pass packs, and proceed through 3 rounds.
Deck Building: UI is ready. Players can filter, build, and add lands.
Next: Need to finalize the "All players ready" logic in deck_building to trigger the actual start_game using the submitted decks. Currently, submitting triggers a placeholder event.
