Refactor: Deep Codebase Improvement

Systematically refactor the codebase for maximum quality.

Targets

1. Dead code — remove all unused code, imports, variables, functions
2. Duplication — extract shared logic, eliminate copy-paste
3. TODOs — resolve or remove every TODO comment
4. Modularity — split large files, extract reusable modules
5. Naming — rename unclear variables, functions, files
6. Types — strengthen typing, remove any, add missing types
7. Structure — reorganize files into logical folders
8. Dependencies — remove unused deps, update outdated ones

Process

Phase 1: Scan

1. Find dead code: unused exports, unreachable code
2. Find duplication: similar code blocks, copy-paste patterns
3. Find TODOs: grep -r "TODO" --include="*.ts" --include="*.tsx"
4. Find large files: files > 300 lines
5. Find weak types: any, missing return types

Phase 2: Refactor

For each issue found:

1. Plan the refactor
2. Make the change
3. Run tests to verify no regression
4. Commit atomically: refactor: description
5. Push immediately

Phase 3: Verify

1. Run full test suite
2. Run type check
3. Run linter
4. Verify build succeeds

Rules

• One logical change per commit
• Tests must pass after each refactor
• No behavior changes — refactor only
• If behavior change needed, separate commit

Exit Condition

• Zero TODOs
• Zero dead code
• Zero duplication
• All tests pass
• All types strict
