The structural piece: a global SequenceMatcher in root_shell, at the
HardwareKeyboard level so a focused editor/pane can't swallow the second
chord. It only STARTS on a modified chord that prefixes a sequence (ctrl+w),
so bare-key sequences (gg, dd) stay editor/pane-local and single-chord presets
are untouched; bare ctrl+w still fires editor.close after the D-82 timeout.
vim.yaml binds the window family under vim.normal||vim.visual: ctrl+w h/l →
panel.focus.left/right, j → dock.toggle, w / ctrl+w → focus.nextPanel,
shift+w → focus.previousPanel, o → panel.focusMode, q/c → editor.close.
Tests: ctrl+w sequence resolution at the keymap layer, plus app-level
integration (ctrl+w o toggles focus mode; bare ctrl+w closes the editor after
the timeout; a bare g is not grabbed globally).
This is the global matcher T-405 part 2 (gt/gT) was waiting on — though bare-g
sequences need more thought (g is editor-local), noted for that follow-up.

The structural T-403 child: make vim normal mode mean navigation in panes
that were mouse-only. The passive global key path can't run multi-chord
sequences (D-82), so each pane hosts its own SequenceMatcher — factored into
a reusable PaneKeyNav that resolves the live keymap and dispatches nav.*
intents while a pane holds focus under the vim preset.
- nav.* intents (down/up/pageDown/pageUp/top/bottom/expandOrRight/
collapseOrLeft/activate) — preset-neutral; vim.yaml binds j/k/ctrl+d/ctrl+u/
gg/G/l/h/[o,enter] under `vim.normal && !editor.focused`.
- The editor publishes an `editor.focused` scope flag from its focus node, so
the same keys stay buffer motions while the editor is focused and become nav
when a pane is — resolved by file order + the guard (no change to the editor
motion bindings).
- File tree: a flattened visible-index selection cursor in FileTreeController
(j/k move, h collapse-or-out, l expand-or-into, o/enter open), with a focus
ring + scroll-into-view.
- Conversation: j/k line-scroll, ctrl+d/u half-page, gg top, G bottom — G
re-arms follow-tail.
Foundation for T-404/T-405/T-407, which build on the per-pane matcher and the
editor.focused guard. Git panel + ticket board list nav deferred to a
follow-up (the ticket says lists can trail). Tests: keymap resolution under
both scopes, PaneKeyNav dispatch, the controller selection model, and
end-to-end key-driven nav in both panes.

The chord matcher couldn't represent a bare or double-tapped modifier:
KeyChord.parse required a base key, so `shift shift` failed, and JetBrains
"Search Everywhere" (double-Shift) was unbindable.
Design decision: search-everywhere aliases clide's existing quick-open
finder (not a new overlay) — bound across all four presets per the user.
Changes:
- KeyChord: a bare modifier name (`shift`, `ctrl`, `cmd`, …) parses as a
modifier-free chord on that modifier's logical key, so parseSequence(
'shift shift') yields a two-chord double-tap. Adds KeyChord.bareModifier
and modifierForLogicalKey.
- ModifierTapTracker: headless, clock-injected double-tap detector. A bare
modifier never forms a single chord; an intervening key breaks the gesture.
- app.dart global handler feeds bare-modifier KeyDowns to the tracker and,
on a double-tap, resolves the 2-chord sequence via the new
KeymapService.resolveSequence. The existing single-chord path is untouched
(zero behavioural risk to normal keys).
- Presets: default/vim/vscode/jetbrains add `shift shift` → quickOpen.open.
jetbrains header updated (the gesture is now expressible).
Tests: bare-modifier parse/equality/round-trip; tracker window/reset/
different-modifier/consume; each shipped preset resolves double-Shift to
QuickOpenIntent.

T-65 — the capstone of the Vim epic. assets/keymaps/vim.yaml binds the
muscle-memory set guarded on vim.normal/insert/visual: hjkl/w/b/e/0/$/^/
gg/G motions, x/dd/dw/D/yy/p/P/cc/cw edits, i/a/I/A/o/O insert entries,
v + d/y/c in visual, Esc back to normal, and counts via the matcher. App
shortcuts (palette, find, zoom) are carried in the preset so they survive
under Vim.
The editor now feeds Shift chords to the matcher (Vim's capitals: G, D,
A, P, $) while still bubbling Ctrl/Alt/Meta to the global handler. The
keybindings-ui stub gains palette commands (`Keymap: Vim` / `Keymap:
Default`) to switch presets — the user-facing way to turn Vim on.
