Fix lint errors with newer Rust

Plus update to Rust 2024, and clean up crate configs.

Fixes the CI failures seen in #57:

```
warning: a method with this name may be added to the standard library in the future
   --> shared/src/inventory_help.rs:119:10
    |
119 |     file.unlock()?;
    |          ^^^^^^
    |
    = warning: once this associated item is added to the standard library, the ambiguity may cause an error or change in behavior!
    = note: for more information, see issue #48919 <rust-lang/rust#48919>
    = help: call with fully qualified syntax `fs2::FileExt::unlock(...)` to keep using the current method
    = note: `#[warn(unstable_name_collisions)]` on by default
```
