List sources

List the sources this documentation is connected to — the repositories and websites its owner registered as its sources of truth, plus the repository the site is built from. Call this BEFORE writing or updating documentation and before judging whether something documented is still true: a connected source is a fact you can go and read, and reading beats recalling. Returns { sources: [{ id, kind, label, url, note, status, origin }] }; note is the owner's own words about why that source is connected — treat it as instruction. Read one with read_source. id is a string, not a number, for two kinds of row that were never 'connected' by hand — it equals origin: workspace_repo is the repository the docs are built from (read it with read_source source_id: "workspace_repo"; arm a commit trigger on it with enable_agent's watch_source_id: "workspace_repo", no need to connect_source it first); site_source is the legacy single URL set in Branding (readable, but not a repository — it cannot be a commit trigger). Every other row's origin is source and its id is a number. An empty list means nothing is connected: say so rather than inventing a repository or a domain. private: true on a row means GitHub will not serve that repository without credentials. It is a READING fact — attach an authorisation, expect no anonymous link to it to work — and it says nothing about whether the published site is public: whether anyone outside can read the DOCS is visibility on the workspace, and a private repository serving a fully indexed public site is an ordinary Docsbook setup.
