Subject: chore(Cargo.toml): Better document direct deps

- Slight adjustments to the version fields for compatibility with
  `cargo +nightly update -Z direct-minimal-versions` for MSRV `1.56.0`
- Add `rust-version` field for leveraging
  `cargo +nightly update -Z msrv-policy` to generate a lockfile that
  respects the MSRV, and the benefit of downstreams.
- Communicate why `dev-dependencies` are required (examples / tests).
- Avoid repeating deps in `dev-dependencies`.
- Raise fixed `warp` dev dep to a MSRV compatible version with common
  `tokio-util` implicit dep. Simplifies CI lock maintenance.
