Refactor ClaudeService to support launching in new terminal window
- Updated `launchClaude` function to handle both headless and interactive modes. - Introduced `launchClaudeInNewTerminalWindow` for launching Claude in a new terminal with rich context. - Modified tests in `ClaudeService.test.ts` to reflect changes in launch methods. - Enhanced `MergeManager` to utilize Claude for conflict resolution, including new tests for this functionality. - Updated `claude.ts` utility functions to accommodate new terminal launch behavior. Fixes #57.
