Enable the full clippy all + pedantic + nursery groups as workspace warnings, with a small documented allow-list for the pedantic/nursery lints this project intentionally does not follow (rustdoc-style requirements, deliberate numeric casts in the protocol/UI layers, and a few noisy nursery lints). Also enable the rust unused_lifetimes and unsafe_op_in_unsafe_fn lints. Fixed every resulting warning (527 -> 0) mechanically per clippy's suggestions: inline format args, const fns, item ordering, let-else, redundant clones, map_or, cast_lossless, Eq derives, associated-fn conversions for methods that never used self, and removing unnecessary Result wrappers whose call sites could never propagate an error. No runtime behavior changed; cargo fmt applied. cargo clippy --workspace --all-targets: 0 warnings. All tests pass.
