fix: simplify Rust pre-commit hooks to avoid cargo metadata errors

The cargo fmt and cargo clippy hooks were failing because cargo was
trying to find Cargo.toml in the root directory before the conditional
checks could run. Simplified the hooks to directly change to the Rust
project directory and exit gracefully if it doesn't exist.
