new-doc

Scaffold a new document with correct frontmatter based on .stem schema. Uses auto-numbering to generate the next ID automatically. This skill should be used when the user says "new doc", "crear documento", "scaffold", "create a new file", "add a document", "nuevo archivo", "add a task", "new record", "nueva tarea", "rootline new", or wants to create a structured document in a rootline-managed directory.
