/**
 * Frontmatter parsing that never throws the file away. pi's `parseFrontmatter`
 * is strict YAML and throws on the kind of thing agent/skill/command authors
 * write by hand (an unquoted colon in a description, a stray tab); a bare
 * `catch` around it silently dropped the whole file (documented trap #7). The
 * lenient fallback reads simple `key: value` lines so the file still loads with
 * whatever could be salvaged. Shared by agents, skills and plugin commands.
