test: Complete Phase 2 card type tests

- Add unit tests for show1cloze card type (6 tests)
- Add unit tests for multicloze variants (12 tests)
- Add integration test for card type system (5 tests)

Phase 2 complete: All major card types tested
Total: 114 tests (98 unit + 16 integration), all passing

+;;; test-card-type-multicloze.el --- Tests for multicloze card type variants
+
+;;; Commentary:
+;; Tests for various multicloze card type variants in org-drill.
+;;
+;; Multicloze variants:
+;; - multicloze (alias for hide1cloze)
+;; - hide1cloze, hide2cloze (hide N clozes)
+;; - show1cloze, show2cloze (show N clozes, hide rest)
+;; - hidefirst, hidelast (hide specific positions)
+;; - hide1_firstmore, show1_lastmore, show1_firstless (weighted variants)
