Add comprehensive pip dependency conflict resolution framework as draft implementation. This is self-contained and does not affect existing ComfyUI Manager functionality. Key components: - pip_util.py with PipBatch class for policy-driven package management - Lazy-loaded policy system supporting base + user overrides - Multi-stage policy execution (uninstall → apply_first_match → apply_all_matches → restore) - Conditional policies based on platform, installed packages, and ComfyUI version - Comprehensive test suite covering edge cases, workflows, and platform scenarios - Design and implementation documentation Policy capabilities (draft): - Package replacement (e.g., PIL → Pillow, opencv-python → opencv-contrib-python) - Version pinning to prevent dependency conflicts - Dependency protection during installations - Platform-specific handling (Linux/Windows, GPU detection) - Pre-removal and post-restoration workflows Testing infrastructure: - Pytest-based test suite with isolated environments - Dependency analysis tools for conflict detection - Coverage for policy priority, edge cases, and environment recovery Status: Draft implementation complete, integration with manager workflows pending.
