* Update preset-fiction-book-writing to community catalog

- Preset ID: fiction-book-writing
- Version: 1.5.0
- Author: Andreas Daumann
- Description: Spec-Driven Development for novel and long-form fiction. Replaces software engineering terminology with storytelling craft: specs become story briefs, plans become story structures, and tasks become scene-by-scene writing tasks. Supports 8 POV modes, all major plot structure frameworks, 5 humanized-AI prose profiles, and exports to DOCX/EPUB/LaTeX via pandoc. V1.5.0: Support interactive, audiobooks, series, workflow corrections

* Add screenwriting preset to community catalog

- Preset ID: screenwriting
- Version: 1.0.0
- Author: Andreas Daumann
- Description: Spec-Driven Development for screenwriting/scriptwriting/tutorials: feature films, television (pilot, episode, limited series), and stage plays. Adapts the Speckit workflow to screenplay craft — slug lines, action lines, act breaks, beat sheets, and industry-standard pitch documents replace prose fiction conventions. Supports three-act, Save the Cat, TV pilot, network episode, cable/streaming episode, and stage-play structural frameworks.
