fix: Add missing adaptors module to pyproject.toml packages

The skill_seekers.cli.adaptors module was missing from the packages list in pyproject.toml, causing ModuleNotFoundError when using the package_skill command with PyPI-installed package (v2.5.0).

This module provides multi-LLM platform support:
- base.py - Base adaptor class
- claude.py - Claude AI adaptor
- gemini.py - Google Gemini adaptor
- openai.py - OpenAI ChatGPT adaptor
- markdown.py - Generic markdown export
