Add multi-click text selection, pending caret formatting and clipboard support, text-aware colour controls, guide/grid snapping, and frame threading with loaded-port interactions. Include the layout, drop-cap and IDML updates carried from #83, with safeguards for generated and linked stories, external text references, local IDs, locked frames and atomic colour edits. Fixes #23. Co-authored-by: Sean Hammond <sean.hammond@und.edu> Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
