Summary:
- Added `codegen-units = 1` and `opt-level = 'z'` to the release profile in `Cargo.toml`
- These changes optimize the build for minimal binary size
Impact:
- Reduces the final binary size by ~7% (244316 -> 228380 bytes)
- Improves resource utilization for embedded systems
- No functional changes to the application behavior

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

Build Rust applictions with cargo is the most commn way,
and it's more easy to cooporate with Rust ecosystem.
This example shows how to use cargo to build a simple hello world
application.
And please notice that you need to install nighly version of rustc
to support this feature, any version after https://github.com/rust-lang/rust/pull/127755
is merged, can use NuttX as cargo target directly.
Build
-----
To build hello_rust_cargo application, you can use any target that based
on RISCV32IMAC, for example:
```
cmake -B build -DBOARD_CONFIG=rv-virt:nsh -GNinja .
```
And disable ARCH_FPU in menuconfig, since the hard coded target triple
in this demo is `riscv32imac`.
