Retro Tools 2026 v0.1.4

[0.1.4] - 2026-08-14

Fixed

• CI was red on every commit since early in the project and had gone unnoticed because local checks never ran with the same strict flags: cargo clippy --workspace --all-targets -- -D warnings failed on two long-standing warnings (ThemePreference's and ToastManager's manual Default impls, both now #[derive(Default)]; ToastManager::report was genuinely unused code and removed), and cargo fmt --all -- --check failed across most of the codebase (now reformatted to rustfmt defaults, no behavior change)
