fix: enhance error output validation to detect incorrect configurations

Browse Source 
- Add validateErrorOutputConfiguration method to detect when multiple nodes are incorrectly placed in main[0]
- Fix checkWorkflowPatterns to check main[1] for error outputs instead of outputs.error
- Cross-validate onError property matches actual connection structure
- Provide clear error messages with JSON examples showing correct configuration
- Use heuristic detection for error handler nodes (names containing error, fail, catch, etc.)
- Add comprehensive test coverage with 16+ test cases
- Bump version to 2.12.1

Fixes issues where AI agents would incorrectly configure error outputs by placing multiple nodes in the same array instead of separating them into success (main[0]) and error (main[1]) paths.

## [Unreleased]
## [2.12.1] - 2025-09-22
### Fixed
- **Error Output Validation**: Enhanced workflow validator to detect incorrect error output configurations
- Detects when multiple nodes are incorrectly placed in the same output array (main[0])
- Validates that error handlers are properly connected to main[1] (error output) instead of main[0]
- Cross-validates onError property ('continueErrorOutput') matches actual connection structure
- Provides clear, actionable error messages with JSON examples showing correct configuration
- Uses heuristic detection for error handler nodes (names containing "error", "fail", "catch", etc.)
- Added comprehensive test coverage with 16+ test cases
### Improved
- **Validation Messages**: Error messages now include detailed JSON examples showing both incorrect and correct configurations
- **Pattern Detection**: Fixed `checkWorkflowPatterns` to check main[1] for error outputs instead of non-existent outputs.error
- **Test Coverage**: Added new test file `workflow-validator-error-outputs.test.ts` with extensive error output validation scenarios
## [2.12.0] - 2025-09-19
