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 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
