fix(ci): install rustfmt and clippy components

The CI was failing because rustfmt is not installed by default in
the rust:latest Docker image.

Error: 'cargo-fmt' is not installed for the toolchain '1.94.0'

Solution:
- Add 'rustup component add rustfmt clippy' step
- This installs both rustfmt and clippy before running lint checks

This allows the fmt and clippy checks to run successfully.
