The Action.schema field needs to be required due to MCP compatibility issues. Please revert this change. The other config optionality change is fine

@michaelessiet I made the requested changes.

The only place where this might cause errors is for the actions that reference the config, for example agent.config.HELIUS_API_KEY, however I think it's not a breaking change since to use these actions the developer is required to pass in the required parameters through the configOrKey object anyway.

Ok.

Please make sure to add the optional operator to any references of agent.config.*. Should be agent.config?.* since config is now optional, and please update the definition within the SolanaAgentKit class. These changes will improve readability and help future contributors understand that config isn't always defined.
