perf: Replace third-party crates with Rust std lib equivalents (#11569) ## Summary Replaces four third-party Rust crates with their Rust 1.80+ standard library equivalents, reducing external dependencies while maintaining identical functionality. ### Replacements | Crate | Replacement | Usages | |-------|-------------|--------| | `atty` | `std::io::IsTerminal` | 6 | | `lazy_static` | `std::sync::LazyLock` | 12 | | `once_cell` | `std::sync::OnceLock`/`LazyLock` | 2 | | `num_cpus` | `std::thread::available_parallelism` | 5 | ### Testing - `cargo check --all-targets` passes - Tests pass for all modified crates ### Notes - `async_once_cell` in `turborepo-repository` was not replaced as there is no std equivalent for async lazy initialization - The `IsTerminal` trait must be imported (`use std::io::IsTerminal`) to call `.is_terminal()` on stdio handles - `available_parallelism()` returns `Result<NonZeroUsize>`, handled with `.map(|n| n.get()).unwrap_or(1)`
