Adds test/terminal/ui/ui_pure_test.dart — 39 unit tests covering the lib/src/terminal/src/ui/ files that don't need a Flutter widget harness. Files at 100%: - palette_builder.dart: 0/52 → 52/52 (named-colour mapping for indices 0..15, RGB cube walk for 16..231 with the 95-then-+40 step pattern, grayscale ramp 232..255, out-of-range clamp). - paragraph_cache.dart: 2/22 → 22/22 (LRU promotion on read, eviction at maxSize, miss returns null, clear empties). - terminal_text_style.dart: 7/19 → 19/19 (default ctor, fromTextStyle fontFamily fallback chain + size/height pass- through, toTextStyle attribute threading, copyWith with override + no-args clone). - input_map.dart: 8/20 → 20/20 (keyToTerminalKey hits + null on unmapped LogicalKeyboardKey id, charToTerminalKey case-fold + multi-char/unknown null). - terminal_size.dart: 4/8 → 8/8 (operator==/hashCode/toString, identity + type-mismatch branches). - pointer_input.dart: 1/3 → 3/3 (default ctor, .none(), .all()). - terminal_theme.dart: 1/1 unchanged. - char_metrics.dart: 0/10 → 10/10 (positive width/height, monotonic text-scaler scaling). - ui/controller.dart: 18/52 → 52/52 (TerminalController default state, setSelection + mode override, attached/detached anchor selection-getter behaviour, prior-anchor disposal on second setSelection, setSelectionMode no-op short-circuit, clearSelection, setPointerInputs / setSuspendPointerInput gating, highlight register/dispose lifecycle, TerminalHighlight.range null on detached anchors). Enums (selection_mode, cursor_type) and themes constants are covered transitively — they have no executable lines that lcov instruments. Coverage delta: - Total project: 67.06% → 68.80%; coverage_floor bumped 66 → 68. Co-Authored-By: Claude <noreply@anthropic.com>
