Module middleware 

DEPRECATED: Stream-based guidance replaces middleware

This module is kept for historical reference only. Error guidance is now provided via PlexusStreamEvent::Guidance events in error streams.

Migration: Frontends should handle guidance events instead of parsing JSON-RPC error data. See the frontend migration guide at: docs/architecture/16680880693241553663_frontend-guidance-migration.md

Architecture: See stream-based guidance design at: docs/architecture/16680881573410764543_guidance-stream-based-errors.md

Structs
