Add tests for `keybindings.dart` (KeyEvent → Keybinding mapping,
parse-error edges, resolver entries view), `toolchain_paths.dart`
(the Flutter-free `ToolchainView.resolved` static view), and several
`widgets/src/` primitives: tooltip hover/overlay, palette filter +
submit, multitab controller `copyWith` + size getters, and additional
markdown branches (h3–h6 headings, tables, strikethrough, default
block fallback, record-link tap).
Unfreezes the pre-push coverage floor that was held at 90 on
2026-05-14 by mistake and ratchets to 93. Tidies eight test files
that had accumulated unused imports flagged by `unnecessary_import`.

12 widget tests in test/widgets/zero_coverage_widgets_test.dart
covering six widgets that had 0% coverage:
- ClidePalette: closed → SizedBox.shrink; open → input + command
list rendered; tap-to-invoke.
- ClideFilterBox: debounced onChanged (timer-flushed), clear button
visibility + reset, onSubmitted forward.
- ColumnHat: left / center / right factories all render; center
label joins project + branch with " > " separator; falls back to
"clide" when neither set.
- ClideIconRail: one button per item, semantics labels, onSelect
fires on tap.
- ClideSpine: label rotation + badge dot + onExpand tap; right-side
variant.
- ClideResizeBorder: wraps child + renders 8 resize zones.
Coverage (totals lifted by these + the prior stale-lcov merge): jumps
from 83.92% to 86.58%. Floor bumped to 86.
Target reset to 90% per user direction: keep grinding sub-areas
until total clears 90%, then keep pushing as reasonable.
