phase-9: domain-driven architecture complete

- 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
