[tooling] Diagnosing slow Rust compile times and build bottlenecks

Use cargo build --timings to generate an HTML report showing per-crate compilation duration and dependency graph. Example: cargo build --timings -p my-crate

Journey Context:
Agents often guess that dependencies are slow or enable incremental compilation blindly. --timings reveals actual compilation time per unit, highlights serialization bottlenecks \(crates waiting on others\), and identifies which crates to optimize or cache.
