story-to-screenplay

• Added a Section Workbench for Blueprint, Script, and Notes so the user can split generated work, edit sections separately, save, rebuild, delete a section, or start over. • Added an Agentic Co-Writer chat panel with saved conversation history and story-aware responses. • Strengthened the ghostwriter prompts for grammar cleanup, full manuscript/script expansion, author questions, and Final Draft-style screenplay formatting. • Improved the local fallback engine with basic grammar polishing and richer screenplay pages with scene headings, action, dialogue, climax, final image, and print-ready structure. • Auto-splits newly generated drafts into editable sections after generation. • Kept export/print/share support working.
