feat(rfc): add Sections 14-18 — errors, config, registry, streams, data/drive
Complete coverage of every core/go primitive:
- Section 14: Error handling (core.E, Wrap, Root) + Logging (Info, Warn, Security)
- Section 15: Configuration (Config.Set/Get/String/Int, feature flags)
- Section 16: Registry[T] (workspace tracking, cross-cutting queries)
- Section 17: Stream helpers (ReadAll, WriteAll, CloseStream)
- Section 18: Data (embedded assets) + Drive (transport config)
22 sections total. Every core/go primitive mapped to core/agent usage.
Next session loads this + core/go RFC → complete domain context.
