- Restructured server layer with 5 domains: shared, screener, portfolio, calls, finance - Migrated 58 TypeScript files to domain-driven structure - Updated CLAUDE.md with new architecture documentation - Added .gitignore rules for .md files (except CLAUDE.md) - Removed unused CatalystAnalyst import from app.ts - Fixed lint errors: removed unused imports, fixed regex escape, added console suppressions - Verified no sensitive data in git history - Server code compiles cleanly with TypeScript strict mode
