Phase 0: Rust project scaffolding (M0 complete)

Completed Rust project initialization:
- Cargo.toml with all dependencies (actix-web, tokio, rustls, etc.)
- Project structure (src/, tests/, configs/)
- Module declarations (api, auth, config, jobs, logging, packages, systemd)
- Clippy and rustfmt configured
- Initial lib.rs and main.rs with logging setup
- Config examples (config.yaml.example, whitelist.yaml.example)

Dependencies resolved and project compiles successfully.
Rust toolchain 1.94.1 installed.
