refactor(protocol): switch runtime to protocol wire codec paths

Point the build and dummy runtime producer at the canonical protocol module so runtime ownership matches the refactored directory structure.

- compile src/protocol/wire_codec.cpp
- update frame source to include and use protocol::wire_codec
- remove remaining sim/wire usage from runtime code
