Adds test/terminal/terminal_view_test.dart — 14 widget tests
covering the StatefulWidget that wires gesture / keyboard / scroll
plumbing around a `Terminal`:
- Construction smoke tests (default, externally-supplied
controller / focusNode / scrollController, hardwareKeyboardOnly,
readOnly + hardwareKeyboardOnly).
- Pointer-signal handling: PointerScrollEvent → PgUp/PgDown
keyInput; non-scroll PointerSignalEvent ignored.
- didUpdateWidget swap of focusNode / controller / scrollController
(auto-created previous instance gets disposed cleanly).
- Hardware key event flowing through to Terminal.keyInput.
- cursorRect / globalCursorRect after layout.
- requestKeyboard / closeKeyboard as no-ops when no edit state is
mounted; hasInputConnection false when no input connection is
open.
- Selection survival when the widget unmounts but an
externally-owned controller stays alive.
Coverage delta:
- terminal_view.dart: 0/188 → 151/188 (80.3%).
- Total project: 59.82% → 65.76%; coverage_floor bumped 59 → 65.
The remaining ~20% in terminal_view.dart sits in
gesture / IME / keyboard-event plumbing (`_onTapUp`, `_onTapDown`,
secondary-tap callbacks, `_onInsert`, `_onComposing`,
`_handleKeyEvent` shortcut path, `_onKeyboardShow`,
`_onEditableRect`, `_scrollToBottom`). These are reachable only
through full pointer / IME simulation that's better suited to
`integration_test/` than widget tests — leaving them for a
later integration-test pass rather than papering over with
brittle gesture mocking.
