Proxy Pattern

Provide surrogate for another object to control access. Proxy has same interface as real object. Adds behavior transparently.

ikigai Application

Potential uses:

Lazy loading: Database connection proxy that connects on first query, not at startup.

Logging proxy: Wrap LLM client to log all requests/responses without modifying client code.

Caching proxy: Cache repeated database queries or LLM responses.

Rate limiting: Proxy that throttles API calls.

Implementation: Proxy struct holds pointer to real object, implements same interface, adds behavior before/after delegating.

Current status: Not explicitly used yet. Consider when adding cross-cutting concerns to existing interfaces without modification.
