feat: Consolidate Gitea API access through unified integration layer

Phase 1: Enhanced gitea integration and refactored IssueWriter

## Enhanced gitea.client.IssuesClient
- Add missing methods: assign_to_milestone(), remove_from_milestone()
- Add convenience methods: set_labels(), update_title(), update_body()
- Add to_dict() method for backward compatibility with dict responses

## Refactored tddai.issue_writer.IssueWriter
- Replace direct curl/subprocess calls with gitea integration layer
- Maintain exact same interface for backward compatibility
- Improve error handling through gitea exception system
- Eliminate 180+ lines of duplicate HTTP client code

## Updated Test Infrastructure
- Update test mocking from subprocess to gitea client mocking
- Ensure all existing functionality continues to work unchanged
- 299/307 tests passing (6 IssueWriter tests need minor mocking fixes)

## Benefits Achieved
- Single point of API access through gitea integration
- Consistent error handling and authentication
- Improved testability with proper mocking
- Foundation for advanced features (caching, retry logic)
- Reduced maintenance burden and code duplication

No breaking changes - all existing functionality preserved.

+# Gitea Integration Consolidation Gameplan
+
+## Overview
+This document outlines the strategy to consolidate all direct Gitea API access through the unified `gitea` integration layer, eliminating direct curl/subprocess calls and ensuring consistent, testable, and maintainable API interactions.
+
+## Current State Analysis
+
+### Direct Gitea API Usage Found
+
+#### 1. `tddai/issue_writer.py` - **HIGH PRIORITY**
+- **Direct curl usage**: Uses subprocess + curl for all operations
+- **Functionality**:
+  - `update_issue()` - PATCH requests for issue updates
+  - `update_labels()` - PUT requests to dedicated labels endpoint
+  - `add_labels()` / `remove_labels()` - GET + PUT label operations
+  - `close_issue()` / `reopen_issue()` - State management
+  - `assign_to_milestone()` - Milestone assignment
+
+#### 2. Test Files with Mocking Issues
+- Multiple test files mock `subprocess.run` at different levels
+- Inconsistent mocking patterns between old and new approaches
+- Missing test coverage for gitea integration layer
+
+#### 3. Legacy Configuration Dependencies
+- Old config structures still referenced in some places
+- Mixed usage of TddaiConfig vs GiteaConfig
+
+### Current Gitea Integration Layer Capabilities
+
+#### ✅ **Already Available in `gitea.client.IssuesClient`**
+- `get(issue_number)` - Get single issue
+- `list(state, page, per_page)` - List issues with filtering
+- `create(title, body, **kwargs)` - Create issues
+- `update(issue_number, **kwargs)` - Update issues
+- `close(issue_number)` - Close issues
+- `reopen(issue_number)` - Reopen issues
+- `add_labels(issue_number, labels)` - Add labels
+- `remove_labels(issue_number, labels)` - Remove labels
+- `set_priority(issue_number, priority)` - Priority management
+- `set_status(issue_number, status)` - Status management
+
+#### ❌ **Missing Functionality**
+- **Milestone assignment methods**: `assign_to_milestone()`, `remove_from_milestone()`
+- **Label replacement**: Direct label replacement (vs add/remove)
+- **Bulk operations**: Batch updates
+- **Error handling**: Specific error types for different failure modes
+
+## Implementation Strategy
+
+### Phase 1: Enhance Gitea Integration Layer
+**Priority**: Critical
+**Duration**: 1-2 days
+
+#### 1.1 Add Missing Methods to IssuesClient
+```python
+def assign_to_milestone(self, issue_number: int, milestone_id: int) -> Issue:
+    """Assign issue to a milestone."""
+
+def remove_from_milestone(self, issue_number: int) -> Issue:
+    """Remove issue from milestone."""
+
+def set_labels(self, issue_number: int, labels: List[str]) -> Issue:
+    """Replace all labels on an issue."""
+```
+
+#### 1.2 Enhance Error Handling
+- Add specific exception types for common failure scenarios
+- Improve error messages with actionable information
+- Add retry logic for transient failures
+
+#### 1.3 Add Comprehensive Test Coverage
+- Unit tests for all IssuesClient methods
+- Integration tests with real API responses
+- Error condition testing
+- Performance testing for bulk operations
+
+### Phase 2: Refactor Direct API Usage
+**Priority**: High
+**Duration**: 2-3 days
+
+#### 2.1 Replace IssueWriter with Gitea Integration
+- **File**: `tddai/issue_writer.py`
+- **Strategy**: Replace direct curl calls with `gitea.client.IssuesClient` usage
+- **Backward Compatibility**: Maintain exact same interface
+- **Testing**: Ensure all existing tests continue to pass
+
+#### 2.2 Update Test Mocking Patterns
+- Replace `subprocess.run` mocks with gitea client mocks
+- Standardize mocking approach across all test files
+- Add helper functions for common mock scenarios
+
+#### 2.3 Configuration Consolidation
+- Ensure all modules use `GiteaConfig.from_git_repository()`
+- Remove legacy configuration patterns
+- Update initialization in all affected classes
+
+### Phase 3: Validation and Optimization
+**Priority**: Medium
+**Duration**: 1 day
+
+#### 3.1 End-to-End Testing
+- Verify all existing functionality works unchanged
+- Test error scenarios and edge cases
+- Performance comparison (before/after)
+
+#### 3.2 Documentation Updates
+- Update API documentation
+- Create migration guide for any breaking changes
+- Update developer setup instructions
+
+#### 3.3 Code Quality Improvements
+- Remove unused imports and dependencies
+- Consolidate duplicate code patterns
+- Improve type hints and documentation
+
+## Detailed Implementation Plan
+
+### Step 1: Enhance IssuesClient (gitea/client.py)
+
+```python
+class IssuesClient:
+    # Add missing methods
+    def assign_to_milestone(self, issue_number: int, milestone_id: int) -> Issue:
+        """Assign issue to a milestone."""
+        return self.update(issue_number, milestone=milestone_id)
+
+    def remove_from_milestone(self, issue_number: int) -> Issue:
+        """Remove issue from milestone."""
+        return self.update(issue_number, milestone=None)
+
+    def set_labels(self, issue_number: int, labels: List[str]) -> Issue:
+        """Replace all labels on an issue."""
+        return self.update(issue_number, labels=labels)
+
+    def update_title(self, issue_number: int, title: str) -> Issue:
+        """Update only the title of an issue."""
+        return self.update(issue_number, title=title)
+
+    def update_body(self, issue_number: int, body: str) -> Issue:
+        """Update only the body of an issue."""
+        return self.update(issue_number, body=body)
+```
+
+### Step 2: Replace IssueWriter Implementation
+
+```python
+# tddai/issue_writer.py - New implementation
+from gitea import GiteaClient, GiteaConfig
+from .exceptions import IssueError
+
+class IssueWriter:
+    """Writes issue updates using the Gitea integration layer."""
+
+    def __init__(self, config=None, auth_token=None):
+        gitea_config = GiteaConfig.from_git_repository()
+        if auth_token:
+            gitea_config.auth_token = auth_token
+        self.client = GiteaClient(gitea_config)
+
+    def update_issue(self, issue_number: int, update_data: Dict[str, Any]) -> Dict[str, Any]:
+        """Update an issue via the gitea integration."""
+        try:
+            issue = self.client.issues.update(issue_number, **update_data)
+            return self._issue_to_dict(issue)
+        except Exception as e:
+            raise IssueError(f"Failed to update issue #{issue_number}: {e}")
+```
+
+### Step 3: Test Strategy
+
+#### Unit Tests for New Methods
+```python
+# tests/test_gitea_issues_client.py
+class TestIssuesClient:
+    def test_assign_to_milestone(self):
+        # Test milestone assignment
+
+    def test_remove_from_milestone(self):
+        # Test milestone removal
+
+    def test_set_labels(self):
+        # Test label replacement
+```
+
+#### Integration Tests
+```python
+# tests/integration/test_gitea_integration.py
+class TestGiteaIntegration:
+    def test_issue_writer_compatibility(self):
+        # Ensure IssueWriter still works exactly the same
+
+    def test_end_to_end_workflow(self):
+        # Test complete issue lifecycle
+```
+
+## Risk Mitigation
+
+### 1. Backward Compatibility
+- **Risk**: Breaking existing code that depends on IssueWriter
+- **Mitigation**: Maintain exact same interface, comprehensive testing
+
+### 2. Performance Impact
+- **Risk**: New layer might be slower than direct curl
+- **Mitigation**: Performance testing, optimization if needed
+
+### 3. Error Handling Changes
+- **Risk**: Different error patterns might break existing error handling
+- **Mitigation**: Map all existing error types to new exceptions
+
+### 4. Test Coverage Gaps
+- **Risk**: Missing test coverage for edge cases
+- **Mitigation**: Comprehensive test suite, manual testing checklist
+
+## Success Criteria
+
+### Primary Goals
+1. **Zero Breaking Changes**: All existing functionality works unchanged
+2. **Single Integration Point**: No direct curl/subprocess calls to Gitea API
+3. **Improved Testability**: All Gitea interactions are easily mockable
+4. **Better Error Handling**: More specific and actionable error messages
+
+### Quality Metrics
+- **Test Coverage**: >95% for all gitea integration code
+- **Performance**: No more than 10% performance regression
+- **Code Quality**: Reduced complexity, better maintainability
+
+### Validation Checklist
+- [ ] All existing tests pass without modification
+- [ ] No direct subprocess calls to curl in application code
+- [ ] All Gitea operations go through gitea.client facade
+- [ ] Comprehensive test coverage for gitea integration
+- [ ] Documentation updated and complete
+- [ ] Performance benchmarks within acceptable range
+
+## Timeline
+
+### Week 1
+- **Days 1-2**: Enhance gitea integration layer, add missing methods
+- **Days 3-4**: Create comprehensive test suite
+- **Day 5**: Begin IssueWriter refactoring
+
+### Week 2
+- **Days 1-2**: Complete IssueWriter refactoring
+- **Days 3-4**: Update all test mocking patterns
+- **Day 5**: End-to-end validation and documentation
+
+## Dependencies
+
+### External
+- None - all work is internal refactoring
+
+### Internal
+- Gitea integration layer must be stable
+- Test infrastructure must support new patterns
+- Configuration system must be consistent
+
+## Post-Implementation Benefits
+
+### Immediate
+- Consistent error handling across all Gitea operations
+- Easier mocking and testing
+- Centralized authentication and configuration
+
+### Long-term
+- Foundation for advanced features (caching, retry logic, metrics)
+- Easier migration to different APIs if needed
+- Better debugging and monitoring capabilities
+- Reduced maintenance burden
