// Package skills persists resource-runtime Skill collections, their
// repository branch pins, agent bindings, and human/workspace grants.
//
// Authorization policy and business behavior belong to the resource Skill
// service, and HTTP contracts belong to the API layer. These persistence types
// are not interchangeable with repo-native Skill definitions, AgentTeam agent or
// workflow skills, generic repository bindings, or API request/response DTOs.
