-Refactoring the protocol stack into something similar to a runtime. -Handles merging handler builders which is placing the ground work for plugins in. - Increased metadata generation during compilation enables less ser/de during execution. - Goal is to have an O(1) time from incoming operation to calling handlers. - Decreased penalty for using the statically typed API from within your code, now avoids some allocation. # Changes - Added `GiteratedRuntime` which is to replace the current unified stack - Added `RuntimeBuilder` which does what the current `OperationHandlers` struct does, but much better. - Added `RuntimeMetadata` to store type metadata for new `Any` based internals - Refactored serde_json out of the internal operation handling
