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.

Raise the declared minimums in pubspec.yaml to what our deps already
require: Flutter >=3.35.0 / Dart >=3.9.0 (was 3.19.0 / 3.5.0). alchemist
0.12 needs Flutter 3.32; Dart 3.9 first ships in Flutter 3.35, so 3.35 is
the binding floor. Pin the exact build toolchain in .fvmrc (Flutter
3.44.1).
Moving to the Dart 3.9 language level switches `dart format` to the new
"tall" style and enables two new lints. This commit is the resulting
mechanical churn, isolated from any behaviour change:
- whole-tree `dart format` reformat (tall style)
- `dart fix` for unnecessary_underscores + use_null_aware_elements
No runtime behaviour change; `make test` green.

T-206. A pure motion/edit engine (vim_edit_ops.dart) operates on
(text, selection, register) and returns the new value plus an
insert-mode request — hjkl/w/b/e/0/^/$/gg/G motions, x/dd/D/dw/yy/p/P/
cc/cw/o/O edits, i/a/I/A insert entries, and d/y/c over a visual range.
It's headless, so the whole grammar is unit-tested in isolation.
The editor wires it in: in normal/visual mode bare keys feed the
SequenceMatcher (modified chords bubble to the global handler for the
palette etc.), a fired editor.vim.* intent applies the op count times
and persists through the existing edit path, and vim.mode.* intents go
to the registry. Crucially the EditableText is read-only in command
mode — on desktop printable keys arrive over the TextInput channel
separately from KeyEvents, so swallowing the key event alone wouldn't
stop them typing; read-only does, while our edits still drive the
controller directly.
