feat: add caching category to Rust ecosystem

[Marve10s]

Summary

• Add RustCachingSchema = z.enum(["moka", "redis", "none"]) as a new category in the Rust ecosystem
• moka: High-performance concurrent in-memory cache (Java Caffeine-inspired, used by crates.io). Crate: moka = { version = "0.12", features = ["future"] }
• redis-rs: Official Redis client for Rust with async support and connection pooling. Crate: redis = { version = "0.29", features = ["aio", "tokio-comp"] }
• Full ~30-file new-category wiring following the checklist: schemas, types, option-metadata, CLI prompts, MCP server (6 spots), web builder (constant, preview-config, stack-defaults, stack-url-keys, stack-url-state, stack-utils), compatibility, bts-config, constants, command-handlers, generate-reproducible-command, config-processing, post-installation, readme-generator, smoke test wiring (options.ts, presets.ts), and tests
