Implement autonomous repository overseer with 7-domain analysis engine

[Copilot]

Adds a modular overseer system that autonomously analyzes repositories across code quality, documentation, dependencies, CI/CD, issues, automation, and monitoring.

Architecture

Core modules (overseer/):

• orchestrator.py - Coordinates multi-domain analysis pipeline
• code_analyzer.py - AST-based refactoring/architecture/performance detection
• doc_generator.py - Auto-generates README/CONTRIBUTING/API docs from code
• dependency_manager.py - Vulnerability scanning with upgrade recommendations
• cicd_optimizer.py - Workflow analysis (caching, matrix, artifacts)
• issue_triager.py - Pattern-based labeling with priority inference
• automation_engine.py - Script generation (formatting, releases, setup)
• monitor.py - Real-time health metrics and actionable recommendations

Interfaces:

• run_overseer.py - CLI supporting full/targeted analysis modes
• demo_overseer.py - Live demonstration of all capabilities

Usage

from overseer import RepositoryOverseer

overseer = RepositoryOverseer('/path/to/repo')
results = overseer.run_full_analysis()

# Or targeted analysis
code_issues = overseer.analyze_code()
# Returns: refactoring opportunities, architectural improvements, 
#          performance issues, quality score

# CLI usage
python run_overseer.py                    # full analysis
python run_overseer.py --only code        # targeted
python run_overseer.py --repo /custom/path

Key Implementations

Code Analysis: Python AST walker detects long functions (>50 LOC), god classes (>20 methods), code duplication, complex conditionals, magic numbers, missing docstrings, and performance anti-patterns (inefficient loops, string concatenation).

Issue Triaging: Regex-based pattern matching across 8 categories (bug, enhancement, documentation, performance, security, dependencies, ci/cd, testing) with 4-level priority inference (critical, high, medium, low).

CI/CD Optimization: YAML parser analyzes GitHub Actions workflows for missing caching strategies, matrix opportunities, and artifact uploads. Suggests complete workflows when test/lint/deploy pipelines absent.

Dependency Management: Multi-ecosystem parser (Python requirements.txt, JavaScript package.json) with extensible vulnerability database and semantic version comparison for upgrade paths.

Testing

28 unit tests covering all modules (100% pass rate). Test harness uses temporary repositories with synthetic issues to validate detection accuracy.
