chore: ignore .venv and uv.lock in nested plugin directories

Add comprehensive ignore patterns for .venv and uv.lock files
in nested directories, particularly plugins/external/opa/. Updated:
- .gitignore: Added **/.venv and **/uv.lock patterns
- .dockerignore: Added **/.venv and **/uv.lock patterns
- MANIFEST.in: Added prune rules and global-exclude patterns
- plugins/external/opa/.gitignore: Created for local ignores
