/**
 * Minimal `~/.ssh/config` reader for the one-shot host import: Host blocks with
 * `Include` expansion and explicit skip reasons. Values stay raw strings; the
 * store maps them onto a HostPayload.
 *
 * Deliberate simplifications (documented in the package README):
 *   - `Match` blocks are skipped — their options are conditional and must never
 *     merge into the Host block above them.
 *   - A multi-pattern `Host a b` line only exposes its first pattern.
 *   - Include pathnames accept `~`, globs, and several whitespace-separated
 *     pathnames, but not environment variables, `%` tokens, or quoting.
 *   - Relative Include pathnames resolve against the directory of the config
 *     file the import started from (OpenSSH: `~/.ssh` for a user config).
 *   - A file that already contributed lines is never read twice, which doubles
 *     as the Include cycle guard.
