fix: Phase 1 critical sim fixes — BUG-01, BUG-02, BUG-05 (#82, #84)

BUG-01: Unknown cards no longer default to "Creature". enrich_card() now
sets type_line="Unknown" for cards without Scryfall data. Added
can_attack_or_block() method to Card — only cards with "Creature" in
type_line can participate in combat. Engine combat uses
can_attack_or_block() instead of is_creature().

BUG-02: Implemented get_legal_moves() and apply_move() in
CommanderGameState with actual game logic — land drops, spell casting
(with mana checking), commander casting from command zone, attack
declarations, and instant-speed responses. Replaces the former
pass-only stubs.

BUG-05: Instants and sorceries now go to graveyard after resolution
instead of being placed on the battlefield as permanents. Added
is_permanent(), is_instant(), is_sorcery() helpers to Card model.

Includes 48 new regression tests covering all three bugs plus
integration tests verifying artifacts/unknown cards never appear in
combat. Fixed existing test_engine.py to match current engine API.

-Commander AI Lab — Online Learning Store (SQLite WAL)
-═════════════════════════════════════════════════════
-
-Single-machine backing store for online learning data collected during
-policy inference (``/api/ml/predict`` and ``/api/policy/decide``).
-
-Each prediction request can optionally log the state snapshot and the
-chosen action so that future training runs can incorporate online
-decision data alongside Forge and PPO batches.
-
-Design decisions (Phase 5 architecture follow-up):
-  - SQLite in WAL mode for concurrent readers + single writer, which is
-    the right fit for a single-machine baseline (one API server process).
-  - Separate DB file (``online_learning.db``) to avoid contention with
-    the collection database.
-  - Append-only writes; reads are batched by the dataset builder.
-  - Thread-safe via the Python sqlite3 module's ``check_same_thread=False``
-    and WAL's built-in reader/writer concurrency.
-
-Usage::
-
-    store = OnlineLearningStore()   # uses default path
-    store.init_db()
-
-    # At prediction time:
-    store.record_decision(snapshot_json, action_index, confidence, playstyle)
-
