Add Task

This creates structured task files in a `.specs/tasks/draft/` directory with proper naming conventions and frontmatter. You give it a description like "add validation to form inputs" and it generates a markdown file with an action-oriented title, classifies it by type (feature, bug, refactor, test, docs, chore, ci), and preserves your original request. The file naming is deliberate: lowercase with hyphens plus a type suffix like `.feature.md` or `.bug.md`. It checks for duplicates across draft, todo, in-progress, and done folders. The description field stays empty by design, meant for a later analysis phase. Useful if you're building a task management system on top of file structure rather than using tickets in Jira or Linear.
