rust: tweak Cargo flags for faster `cargo test`
What changed, and why it matters
This commit only changes Rust compiler settings used when running automated tests. It disables link-time optimization, increases parallel compilation units, and turns off optimization to make tests run faster. There is no change to the actual firmware code, no security fix, and no security-relevant behavior change.
No security action needed. This is a benign build/development configuration change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff adds three lines to the [profile.test] section of src/rust/Cargo.toml: lto = false, codegen-units = 256, and opt-level = 0. These are standard development/test profile tuning flags that reduce compile time and are not applied to release firmware builds. They do not alter runtime security properties of shipped firmware.
