greengrass hello-world recipes broken after component-sdk v1.0.1 upgrade

[rpcme]

Problem

The greengrass hello-world sample component recipes fail to build on master after the aws-greengrass-component-sdk v0.4→v1.0.1 upgrade (#15440).

greengrass-component-helloworld-cpp (x86-64)

fatal error: gg/types.hpp: No such file or directory

The SDK v1.0.1 changed its header layout. The C++ hello-world recipe references gg/types.hpp which no longer exists at that path.

greengrass-component-helloworld-rust (arm64)

error: could not compile `hello-world-rust` (bin "hello-world-rust") due to 1 previous error

Likely the Rust crate API changed between v0.4 and v1.0.1 (e.g. Ipc renamed to Sdk).

Impact

• All greengrass hello-world recipes (C, C++, Rust, possibly Python/Bash) may be affected
• Build failures on all architectures for any PR that triggers ptest builds
• Does not affect the core SDK recipe itself (builds fine)

Fix needed

• Update hello-world recipes to use v1.0.1 API and header paths
• Check all 5 hello-world variants: bash, c, cpp, python, rust
• Verify against upstream SDK examples if available
