Add the linebender lint set

Nobody has claimed this yet.

We should add a standardized set of rustc lints and clippy lints to all our projects. If we raise MSRV to 1.74, we can add them directly to `Cargo.toml`.

See [zulip discussion](https://xi.zulipchat.com/#narrow/stream/419691-linebender/topic/Standard.20Lint.20set) for what our lint set should be. See https://github.com/linebender/peniko/pull/47/ for our current lint set.

Aside from the `Cargo.toml` lints, we should also add the following annotation to our crate root:

```
#![warn(clippy::print_stdout, clippy::print_stderr, clippy::dbg_macro)]
```

(We don't want a workspace-level lints for those because we want to tolerate prints in tests and examples.)

See [this zulip thread](https://xi.zulipchat.com/#narrow/stream/419691-linebender/topic/Standard.20Lint.20set) for details.

We should add the following annotation at the crate roots:

We should also remove leftover prints, if any, or give them an opt-out.

Inspect each project's Cargo.toml and crate root, using the peniko pull request and linked Zulip discussion to identify the standardized rustc and Clippy lint set. Check for leftover prints across the projects and determine where an opt-out is needed. Done means every project has the agreed Cargo.toml lints, the crate-root annotations, and no unhandled leftover prints.
