General Maintenance - Code Health & Quality Initiative

### Code Health & Quality Initiative
This is an initiative for sustained health and quality across codebases and projects. Its purpose is to centralize and track all **non-feature** work that improves developer experience, efficiency, and stability.

#### Scope
- Library and Dependency updates (patch, minor, major releases, security, etc).
- Technical debt reduction (refactoring, removal of legacy code).
- Performance enhancements and optimization.
- Documentation creation and updates (internal docs, READMEs).
- General cleanup and code quality improvements.

#### Action
Please create all specific maintenance items (e.g., 'Update dependancy X to latest') as sub-tasks under this parent ticket.

No file, test, or entry point is named, and this issue defines a broad maintenance initiative rather than a discrete change. Start by identifying a specific dependency, cleanup, performance, documentation, or quality task, then create it as a sub-task under this ticket with a bounded completion check.
