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.

Six tests for the last reachable coverage gaps in the terminal tree:
- EscapeParser CSI handlers that read params[0] and normalise 0 → 1:
CUF (ESC [ Ps C), CUB (ESC [ Ps D), CPL (ESC [ Ps F).
- insertLines with an explicit param (ESC [ Ps L).
- DEC private mode 1001 (HighlightMouseTracking) toggles MouseMode
.upDownScroll on, none off.
- RenderTerminal._onScroll driven via a test ViewportOffset that
exposes notifyListeners — verifies the listener body runs without
throwing when an offset is swapped in via the setter.
Coverage: escape/parser.dart 503/513 -> 510/513 (the 3 remaining
lines are _CSI.toString — only reachable from a debug log call that
no production path makes); render.dart 245/249 -> 249/249.
