fix: resolve all MCP CLI test failures achieving 100% pass rate

Root cause analysis and systematic fixes:

1. **CLI Argument Parsing Conflict**: Fixed naming conflict between main parser's
   'command' attribute and MCP configure parser's 'command' argument by renaming
   to 'server_command'

2. **Pydantic Model Validation**: Fixed test configuration to respect MCPServerConfig
   validation rules - cannot specify both 'command' and 'url' simultaneously

3. **Unicode Character Encoding**: Replaced Unicode symbols (✓/✗) with ASCII-compatible
   text ([SUCCESS]/[ERROR]) to prevent Windows console encoding errors

4. **Mock Patch Path Issues**: Corrected import paths in tests to patch the actual
   imported classes rather than their source modules

5. **TTY-aware Confirmation Logic**: Fixed request_confirmation() function to properly
   handle mocked input in test environments while maintaining non-TTY auto-approval

**Test Results**:
- Before: 51/58 passing (87.9% success rate)
- After: 58/58 passing (100.0% success rate)

All originally failing tests now pass:
- TestMCPConfigureCommand.test_configure_argument_parsing_basic ✅
- TestMCPConfigureCommand.test_configure_argument_parsing_with_options ✅
- TestMCPConfigureCommand.test_configure_dry_run ✅
- TestMCPConfigureCommand.test_configure_failed ✅
- TestMCPConfigureCommand.test_configure_successful ✅
- TestMCPRemoveCommand.test_remove_failed ✅
- TestMCPRemoveCommand.test_remove_successful ✅
- TestMCPCLIPackageManagement.test_request_confirmation_user_* ✅

Follows Phase 4 development workflow with systematic debugging approach.
