meta: align Cargo.toml metadata with uutils conventions

- Fix root package edition (2021 → workspace 2024)
- Use workspace inheritance for license, authors, repository, rust-version
- Fix keywords: "coreutils" → "shadow-utils", add "uutils"
- Add homepage, keywords, categories to workspace.package
- Add workspace metadata inheritance to all 15 crate Cargo.toml files
- Normalize tool descriptions to "tool ~ (shadow-rs) verb phrase" format
- Add feat_common_core feature alias (groups all 14 tools)
- Fix pre-existing clippy and fmt issues from edition 2024 alignment
