Pull request overview

This pull request moves the CodeStore effect and related data types from the galley service to the shared wire-subsystems library. This refactoring improves code organization by extracting conversation code functionality into a reusable subsystem that can be shared across services.

Changes:

• Moved CodeStore effect from Galley.Effects.CodeStore to Wire.CodeStore
• Moved Code and Scope data types from Galley.Data.* to Wire.CodeStore.*
• Moved Cassandra implementation from Galley.Cassandra.Code to Wire.CodeStore.Cassandra
• Updated all import statements across galley service to reference the new module locations
