jpmschweitzerandClaude Opus 4.8 6d0ebab721 chore: adopt Dart 3.9 toolchain — honest floor + tall-style reformat (T-353)
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.

/// A non-PTY pane the user sees in the GUI — a kernel tab (Claude, Files,
/// Editor, a viewer) surfaced so `pane list` reflects the live workspace,
/// not only PTY-spawned panes (T-219, D-6 parity / D-83).
///
/// The PTY-backed [Pane] can't represent these: a tab has no child process.
/// Rather than mirror state into [PaneRegistry] (and risk it drifting from
/// the live UI), the kernel snapshots its `PanelRegistry` into these value
/// objects at request time — `pane.list` reads them through an injected
/// source. Pure data, Flutter-free, so it serialises on the IPC wire and
/// stays usable from `dart test`.
