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.

Foundation for rendering the Claude conversation natively (T-132) with
the cross-widget select+copy the terminal gives today. Converts the raw
RichText in clide_markdown + clide_code_block to Text.rich, which
registers with a Flutter SelectionArea's selection machinery (raw
RichText does not). Adds a selectionBackground surface token
(globalFocus at ~40% alpha, matching the terminal's selection tint) via
tokens + resolver default; bundled palettes are untouched (D-69).
Text and code blocks now select across each other under a SelectionArea;
tables and tappable link-spans remain non-selectable islands for now.
The selection contrast pair is intentionally not added to the WCAG gate:
the tint is semi-transparent and the gate's neutral-grey compositor would
false-fail it (documented in contrast.dart); deferred to the -hc/-cb pass.

Each ClideCodeBlock and EditorView created its own TreeSitterService,
each allocating a WASM engine, store, parser, and cursor via FFI.
When widgets were disposed, multiple instances freeing the same
underlying native resources caused double-free corruption on startup.
Single shared instance for the app lifetime. Also fixes overlapping
tree-sitter spans that caused duplicated text in code blocks — spans
are now clipped to avoid re-emitting already-rendered characters.
