refactor: improve testability through dependency injection and test simplification
- Convert Storage to use dependency injection for Logger - Changed constructor to accept Logger as optional parameter - Removed setLogger method to follow constructor injection pattern - Updated all usage sites to pass Logger at construction time - Extract UIProvider interface for better testability - Created UIProvider interface to abstract VS Code UI operations - Implemented DefaultUIProvider for production use - Added createTestUIProvider factory for consistent test mocking - Remove eslint-disable comments and improve type safety - Eliminated 3 eslint-disable comments from commands.test.ts - Fixed all TypeScript type issues without using 'any' - Properly typed all mock functions and test helpers - Consolidate test helpers and remove redundant code - Moved all mock creation to test-helpers.ts - Removed testUIProvider.ts and testUIProvider.test.ts (consolidated) - Removed uiProvider.test.ts (pointless delegation tests) - Added withUrlHistory to mock Storage for complete coverage - Simplify tests and use real objects where possible - Replaced mock-heavy tests with simpler assertions - Used real Logger instances in tests instead of mocks - Removed tests that were testing implementation details This refactoring improves maintainability, follows SOLID principles, and makes the codebase more testable without compromising functionality. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
