Multi-step redo was broken because `getUndoHistoryItem()` cleared the
redo stack whenever the last undo item was sealed — even during redo
operations. After the first redo, the 50ms debounce timer would seal
the item, causing the next redo to wipe the remaining redo history.
Refactored the undo/redo system with:
- `TransactionSource` enum (userEdit, undo, redo, none) replacing
boolean flag combinations in ApplyOptions
- `UndoManager.record()` with symmetric paths for each source:
- userEdit: groups into unsealed items, clears redo on branch
- undo: pushes directly to redo stack
- redo: pushes directly to undo stack (sealed), no redo clear
- Deprecated `getUndoHistoryItem()` and legacy boolean flags
* chore: update Flutter SDK to version 3.38.5
Upgrade Flutter from 3.32.4 to 3.38.5 to meet awesome_lints
requirement for Dart SDK 3.10.0+. Update CI workflow to use
the new Flutter version and add custom_lint verification step.
* chore: integrate awesome_lints with custom lint rules
Add awesome_lints and custom_lint dependencies, configure
analysis_options.yaml to enable newline lint rules: newline_before_case,
newline_before_constructor, newline_before_method, and newline_before_return.
* style: apply newline formatting per awesome_lints rules
Add blank lines before case clauses, return statements, method
declarations, and constructors throughout the codebase to comply
with awesome_lints newline rules.

Update Matrix4.translate() calls to use the new leftTranslateByDouble()
API to resolve deprecation warnings in Flutter SDK 3.38.5.
