refactor: inherit Clippy lint config and Rust edition from workspace (#3782)

* refactor: inherit Clippy lint config and Rust edition from workspace

This also ensures developers running `clippy lint` locally get the same
lints as during CI, especially when the Rust toolchain version is fixed
through a `rust-toolchain.toml` file.

* chore(clippy.toml): bump MSRV to 1.87
