• Added Claude Code settings (.claude/settings.json) with hooks for typecheck, lint, and knip after edits
• Removed unused exports across multiple modules (types, interfaces, constants)
• Removed @types/tar dependency (unused type definitions)
• Updated msw from v2.12.7 to v2.12.10
• Added .worktrees to .gitignore
• Cleaned up telemetry module exports (removed unused PostHog-related exports)
• Made several interfaces and functions internal by removing exports (e.g., RunCommandOptions, CLIError, UserError, SystemError)
• Removed unused error handling code and helper functions

Testing

This refactoring improves code maintainability by identifying and removing unused code/dependencies. The Knip CI workflow will help prevent accumulation of dead code in the future. Changes are purely internal cleanup and do not affect the CLI's behavior or public API.
