Fix Rust version compatibility in Forgejo Actions workflows

- Add Rust version checking to ensure 1.84.1+ requirement is met
- Force install latest nightly toolchain if version is too old
- Consolidate Rust installation and environment setup in simple workflow
- Fix PATH persistence between workflow steps
- Add better error handling and version validation
