/**
 * Behavioral tests for `gsd-tools list-seeds` (#441) — the data layer behind the
 * `/gsd-capture --list-seeds` audit view. Exercises the real CLI via runGsdTools
 * and asserts on the structured JSON contract (count, seeds[], summary), never on
 * rendered prose. Includes the parser/security QA matrix: malformed frontmatter,
 * missing fields, non-seed files, status filtering, and hostile content.
