Very hard to not approve (given that the compiler says it is fine)

Pull Request Overview

This PR refactors the codebase to eliminate mod.rs files by adding the #![deny(clippy::mod_module_files)] lint to enforce using module file names instead of mod.rs files.

• Adds clippy lint to prevent mod.rs usage across all library entry points
• Enforces consistent module organization using individual module files

Thanks.

Just a tip, we alternatively add the the lint to the workspaceCargo.toml file instead of in the source code

[workspace.lints.clippy]
mod_module_files = "forbid"

And inheritance to the workspace members's Cargo.toml files:

[lints]
workspace = true

It's unfortunate that the explicit workspace inheritance is needed for the lints though. There's a tracking issue for automatically inheriting the lints:
rust-lang/cargo#12208

Right, nice. Updated this in 308c39f

Right, nice. Updated this in 308c39f

This caused some clippy errors in the Devnet crate. Probably worth fixing it, but in the interest of not getting stuck on this I reverted and restored the old top level attributes to enforce the lint.

Makes sense. Thanks for trying :)

Created #1005 so we can revisit in the future.
