Implement infrastructure for editing parsed binary fields:
FieldEditCommand (QUndoCommand):
- Undo/redo support for field value changes
- Stores old and new values with field metadata
- Integrates with Qt's undo stack
DirtyStateManager:
- Tracks modified state per-tab
- Emits signals when dirty state changes
- Enables save prompts and tab indicators
ScriptTypeEditorWidget enhancements:
- Add recompilation debouncing (300ms) for responsive editing
- Build form layout only for fields with values (skip unexecuted branches)
- Support edit signals for modified fields
- Improved table and form layout building
