/**
 * Minimal YAML frontmatter reader for skill and agent markdown files.
 *
 * Only flat `key: scalar` maps are needed, but the scalar forms real SKILL.md
 * files use must all work, or a skill silently reaches the catalog with a
 * description like `>` and never gets chosen:
 *
 * - plain values, which may continue on more-indented lines (folded to spaces)
 * - single- and double-quoted values (quotes removed, `''` / `\"` unescaped)
 * - block scalars: `>` folds lines into one, `|` keeps newlines; `-`/`+` chomping
 *   indicators are accepted
 *
 * Keys are lowercased. Nested maps and lists are not interpreted; their text is
 * kept as the value's continuation, which callers ignore for unknown keys.
