/**
 * SKILL.md frontmatter resolution — Agent Skills standard compatibility layer.
 *
 * The Agent Skills standard (agentskills.io) allows exactly six top-level
 * frontmatter fields: name, description, license, compatibility, metadata,
 * allowed-tools. Anything else is rejected by the reference validator
 * (skills-ref) and by Anthropic's Skills API / package_skill.py, which fails
 * with "Unexpected key(s) in SKILL.md frontmatter".
 *
 * agents-market-specific fields therefore live in the `metadata` map under an
 * `io.agentsmarket/` reverse-DNS prefix. The standard defines metadata as
 * map<string, string>, so every value is a quoted scalar; lists are encoded as
 * comma-separated strings.
 *
 * Top-level fields remain accepted as a legacy fallback so skills published
 * before this change keep working.
 */
/** The six top-level fields the Agent Skills standard permits.
 *
 * Sourced from the standard, not invented here: agentskills.io allows exactly
 * `name`, `description`, `license`, `compatibility`, `metadata` and
 * `allowed-tools`, and the reference validator (skills-ref) plus Anthropic's
 * package_skill.py reject anything else with "Unexpected key(s) in SKILL.md
 * frontmatter". `validateSkillContent` below enforces it, because our own
 * resolver does not — it ignores unrecognised keys, so a file carrying one
 * publishes cleanly here and is then refused by every consumer that validates
 * against the standard. That is precisely the failure `skill validate` exists
 * to catch before the upload, not after it.
