Comprehensive Codebase Cleanup and Quality Enhancement Plan

As a code quality improvement specialist, I want you to help me clean up my codebase, which is a complex task that requires collaboration among 8 specialized subagents. Each subagent will handle a specific aspect of code enhancement, as outlined below. Each subagent must: conduct detailed research on their task, provide a critical assessment of the current code, and implement all high-confidence recommendations. The subagents and their tasks are as follows:

1. **Code Deduplication Subagent**: Deduplicate and consolidate all code, implementing the DRY (Don't Repeat Yourself) principle where it reduces complexity. Provide a report detailing the areas of redundancy and recommendations for consolidation.
   
2. **Type Definition Consolidation Subagent**: Identify all type definitions and consolidate any that should be shared. Include a summary of type definitions before and after consolidation.
   
3. **Unused Code Removal Subagent**: Utilize tools like Knip to identify all unused code. Ensure that all identified code is verified to be unreferenced before removal. Include a report on unused code findings.
   
4. **Circular Dependency Resolution Subagent**: Untangle any circular dependencies using tools like Madge. Provide a detailed assessment of the identified dependencies and how they were resolved.
   
5. **Type Strengthening Subagent**: Remove any weak types (e.g., 'unknown', 'any') and research appropriate strong types for replacements. Ensure that there are no type issues and provide a summary of changes made.
   
6. **Error Handling Improvement Subagent**: Remove unnecessary try-catch blocks and other defensive programming patterns that do not serve a specific purpose. Ensure clear error handling is in place, and document the rationale for any removals.
   
7. **Code Cleanup Subagent**: Identify and remove any deprecated, legacy, or fallback code. Aim for clean, concise, and singular code paths in the codebase. Provide a report on the code paths cleaned up.
   
8. **Comment and Documentation Subagent**: Identify and remove any irrelevant comments, including AI-generated stubs and unnecessary annotations. Revise comments that describe ongoing work or past efforts to be concise and helpful for new users.

Each subagent should provide a detailed report of their actions and the outcomes of their improvements in a structured format, including before-and-after comparisons where applicable.
