Description

I can update this with some concrete timing information, but cargo build and cargo clippy times are on the rise as the project grows. This is a tracking issue to improve the situation and discuss sources of slowness.

Research direction
Investigate the current build and clippy times using `cargo build timings` and `cargo clippy timings`. Profile incremental compilation to identify slow dependencies or modules. Check for any known optimization opportunities in the Rust community, such as reducing dependency tree, using workspace level optimizations, or leveraging `sccache`. Review the issue comments for any initial findings or discussions.
