Create managed documentation

Added value: +"Markdown body, written below the frontmatter."

Added value: +"Folder below the managed docs root. Omit to let docs.layout decide; an empty string writes to the root."

Added value: +"What sort of document this is — architecture, runbook, reference and so on. Project-declared, so the accepted values vary; project_workspace reports them."

Added value: +"Who is answerable for keeping this accurate."

Added value: +"IDs of records worth reading alongside this one."

Added value: +"Date after which this goes stale, YYYY-MM-DD. Defaults to docs.reviewIntervalDays from now."

Added value: +"Subject matter this document covers — topics, not file paths."

Added value: +"Where the content came from: a URL, a person, a meeting."

Added value: +"Lifecycle status, typically draft or current. Project-declared, so the accepted values vary; project_workspace reports them."

Added value: +"IDs of documents this replaces. They are marked superseded."

Added value: +"Free-form tags for filtering."

Added value: +"What the document is about, in one line."
