Refactor: Dedupe and Cleanup

Eliminate redundancy and remove dead code.

Deduplication Patterns

1. Extract Common Method

Move duplicated logic to shared function.

2. Template Method Pattern

Abstract common structure, vary details.

3. Consolidate Conditional Expression

Combine conditions with same result.

Dead Code Removal

Types to Remove

1. Unreachable code - after return/throw
2. Unused variables - declared but never read
3. Unused functions - never called
4. Commented code - use git history instead
5. Unused imports - clutters namespace

Safe Removal Process

1. Search for all references
2. Check for reflection/dynamic usage
3. Remove in small commits
4. Run full test suite
