no cmake, no protoc, no problems (#256)

* Simplify setup and build by removing reliance on `cmake` and `protoc`
* [Fixes `Cargo.lock` issue](https://trunk-io.slack.com/archives/C02CMS4TFUJ/p1734464030801369) seen in `context-ruby`
* Fix running Clippy
* Fix running `rust-analyzer`
* Fix `cargo check` lints
* Fix imports of dependencies with inconsistent versions
