contract-new

Author a new Manifest contract from a rough idea, a one-liner, OR a link to an existing source of truth — JIRA ticket, Linear issue, Notion page, Confluence doc, GitHub issue, or Figma file. Use when the user says "new contract", "draft PRD", "spec out a feature", "pull contract from this JIRA ticket", or invokes /contract new with either prose or a URL. Pre-fills as much of the contract as possible from the source, then asks the user only what's still missing.
