Phase 4: Implement Repository Provider Implementation (v0.5.0)

This commit implements Phase 4 of the CHORUS task execution engine development plan,
replacing the MockTaskProvider with real repository provider implementations for
Gitea, GitHub, and GitLab APIs.

## Major Components Added:

### Repository Providers (pkg/providers/)
- **GiteaProvider**: Complete Gitea API integration for self-hosted Git services
- **GitHubProvider**: GitHub API integration with comprehensive issue management
- **GitLabProvider**: GitLab API integration supporting both cloud and self-hosted
- **ProviderFactory**: Centralized factory for creating and managing providers
- **Comprehensive Testing**: Full test suite with mocks and validation

### Key Features Implemented:

#### Gitea Provider Integration
- Issue retrieval with label filtering and status management
- Task claiming with automatic assignment and progress labeling
- Completion handling with detailed comments and issue closure
- Priority/complexity calculation from labels and content analysis
- Role and expertise determination from issue metadata

#### GitHub Provider Integration
- GitHub API v3 integration with proper authentication
- Pull request filtering (issues only, no PRs as tasks)
- Rich completion comments with execution metadata
- Label management for task lifecycle tracking
- Comprehensive error handling and retry logic

#### GitLab Provider Integration
- Supports both GitLab.com and self-hosted instances
- Project ID or owner/repository identification
- GitLab-specific features (notes, time tracking, milestones)
- Issue state management and assignment handling
- Flexible configuration for different GitLab setups

#### Provider Factory System
- **Dynamic Provider Creation**: Factory pattern for provider instantiation
- **Configuration Validation**: Provider-specific config validation
- **Provider Discovery**: Runtime provider enumeration and info
- **Extensible Architecture**: Easy addition of new providers

#### Intelligent Task Analysis
- **Priority Calculation**: Multi-factor priority analysis from labels, titles, content
- **Complexity Estimation**: Content analysis for task complexity scoring
- **Role Determination**: Automatic role assignment based on label analysis
- **Expertise Mapping**: Technology and skill requirement extraction

### Technical Implementation Details:

#### API Integration:
- HTTP client configuration with timeouts and proper headers
- JSON marshaling/unmarshaling for API request/response handling
- Error handling with detailed API response analysis
- Rate limiting considerations and retry mechanisms

#### Security & Authentication:
- Token-based authentication for all providers
- Secure credential handling without logging sensitive data
- Proper API endpoint URL construction and validation
- Request sanitization and input validation

#### Task Lifecycle Management:
- Issue claiming with conflict detection
- Progress tracking through label management
- Completion reporting with execution metadata
- Status updates with rich markdown formatting
- Automatic issue closure on successful completion

### Configuration System:
- Flexible configuration supporting multiple provider types
- Environment variable expansion and validation
- Provider-specific required and optional fields
- Configuration validation with detailed error messages

### Quality Assurance:
- Comprehensive unit tests with HTTP mocking
- Provider factory testing with configuration validation
- Priority/complexity calculation validation
- Role and expertise determination testing
- Benchmark tests for performance validation

This implementation enables CHORUS agents to work with real repository systems instead of
mock providers, allowing true autonomous task execution across different Git platforms.
The system now supports the major Git hosting platforms used in enterprise and open-source
development, with a clean abstraction that allows easy addition of new providers.
