perf(docker): optimize Rust build times with dependency layer caching

Browse Source 
Replace sccache with a two-stage build strategy: dummy source files cache
dependency compilation in a separate layer, and --mount=type=cache for
Cargo registry/git/target directories. Source-only changes now skip
full dependency recompilation.
