- Base type with standard sections (Server, Database, MCIAS, Log) - Duration wrapper type for TOML string→time.Duration decoding - Generic Load[T] with TOML parse, reflection-based env overrides, defaults, required field validation, optional Validator interface - Env overrides: PREFIX_SECTION_FIELD for string, duration, bool, []string (comma-separated) - WebConfig exported for services with web UIs (not embedded in Base) - 16 tests covering full/minimal configs, defaults, env overrides, validation, error cases Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
