Pre-populate npm, cargo, and pip caches during Docker image build time so that first-time package installations are significantly faster. Changes: - base-system.Dockerfile: npm cache add for ~25 common packages (React, Next, Vite, TypeScript, testing, styling, utilities) - intermediate/rust.Dockerfile: cargo fetch for common crates (tokio, serde, anyhow, reqwest, clap, etc.) - generate_docker.js: new generateCacheWarmCommands() function with support for npm, cargo, and pip cache warming in generated Dockerfiles - config.json: updated rust template + added cache_warm configs to ethereum, solana, tangle, universal, and langchain projects Expected impact: - npm install react: ~5s → <1s - npm create vite: ~15s → ~2s - cargo build (new project): ~60s → ~10s Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

- Add chmod -R a+w $CARGO_HOME after cargo fetch to ensure cache files are writable by the project user (not just root) - Add --break-system-packages flag to pip download for consistency with other pip commands and compatibility with newer pip versions Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
