Summary:
- Renamed hello_rust example to rust/baremetal to better reflect its purpose
- Updated file headers and Makefile paths
- Maintained all existing Kconfig options and functionality
- Prepares for future Rust development patterns where Cargo will be the
mainstream approach, with baremetal demonstrating traditional build method
- Creates clearer structure for Rust examples as we expand Rust support
Impact:
- No functional changes to the example itself
- Better organization of Rust examples under examples/rust/
- Existing configurations using this example will continue to work
- Build system will now look for the example in the new location
Testing:
- Confirmed Kconfig options remain unchanged
- GitHub CI passed and local build tested
