nano-ros releases nros 0.6.0-nros3
nano-ros's nros CLI has released 0.6.0-nros3, corresponding to codegen version 18. Per RFC-0097 D7, if another release declares the same codegen version, nothing is regenerated; nros pin first reads both manifests from storage before modifying nros-toolchain.toml, and nros toolchain manifest can print the declarations of an installed toolchain.
