Pull request overview

Moves Azure-specific embedded resources out of the shared core library and updates server startup to explicitly register resources/providers at program initialization.

Changes:

• Updates registry discovery to load registry.json from a specified assembly/resource instead of scanning the executing assembly.
• Introduces pluggable providers for server instructions and consolidated tool definitions (including null/default implementations).
• Updates Azure/Fabric/Template servers to register the new providers and (for Azure) embed and load resource files from the server assembly.
