tegwick 3af6fb9935 feat: Integrate Requirements Engineering Agent and fix Issue #59 test failures
## Major Integration

-  Integrated Requirements Engineering Agent into development workflow
-  Enhanced Makefile with requirements validation targets
-  Added pre-commit validation with mock compatibility checking
-  Enhanced TDD workflow to include foundation analysis

## Test Fixes

-  Fixed GiteaPlugin missing _add_comment_async method
-  Fixed LocalPlugin config.yml file not found errors in tests
-  Enhanced mock objects in CLI tests with proper domain model attributes
-  All Issue #59 tests now passing (38/38 tests pass)

## New Capabilities

- `make validate-requirements` - Foundation analysis before development
- `make check-interface-compatibility INTERFACE=Name` - Interface compatibility checking
- `make generate-dev-checklist FEATURE='Name'` - Development checklist generation
- `make validate-mocks` - Mock object compatibility validation
- `make pre-commit-validate` - Complete pre-commit validation workflow

## Problem Prevention

This integration prevents the exact interface compatibility issues and mock object
mismatches that caused hours of debugging in Issue #59. The Requirements Engineering
Agent provides proactive foundation analysis and catches problems before they occur.
