Agent Skills: b2c-hooks

Implement hooks with HookMgr, hooks.json registration, and system extension points for order, basket, and API lifecycle events. Use this skill whenever the user needs to register a hook implementation, extend OCAPI/SCAPI behavior with before/after hooks, customize order calculation or payment authorization, or create custom extension points. Also use when debugging hook registration or Status return values -- even if they just say 'run code when an order is placed' or 'intercept the basket API'.
