feat: add pre-flight config validation for silently skipped features#100
Conversation
… features Template handlers silently skip features when config combinations are incompatible (e.g., CMS with non-Next.js frontend, Search with Convex backend). Users get zero feedback — selected features simply don't appear in the generated project. Adds a pre-flight validation layer using Effect-ts that runs after config assembly and before template generation, warning users about features that won't produce output. Covers 20+ silent failure scenarios across search, file storage, job queue, email, logging, observability, CMS, payments, analytics, feature flags, API, and database handlers. - CLI: yellow warning box between config assembly and generation - Web: collapsible warning banner in the preview panel - 52 tests covering all rules, edge cases, and multiple warnings
