⚡ Optimize Caching: Use rust-cache Action

Replace manual caching with Swatinem/rust-cache@v2:

**Benefits:**
- ✅ Automatic Cargo registry/index/target caching
- ✅ Platform-specific cache keys (per target)
- ✅ Shared cache between test and build jobs
- ✅ Incremental compilation support
- ✅ Cache-on-failure enabled

**Performance:**
- First build: ~5-10 min (compile everything)
- Subsequent builds: ~1-2 min (only changed files)
- 80-90% faster rebuilds!

This will significantly speed up CI/CD builds.
