Subject: [PATCH] Add [workspace.lints] to manifests

From Rust 1.74 and onwards, this section enables opt-in lints for crates
of this workspace. Read more information at https://blog.rust-lang.org/2023/11/16/Rust-1.74.0.html

For a crate to opt-in, it needs to set

 [lints]
 workspace = true

In its Cargo.toml

Closes #518
