Add /add-parallel skill for Parallel AI integration (#28)

Adds a skill to integrate Parallel AI MCP servers for advanced web research.

What it adds:
- Quick Search MCP for fast web lookups (free to use)
- Task MCP for deep research with scheduler-based polling
- Non-blocking design using NanoClaw's scheduler

Usage: Run /add-parallel to add this integration to your fork

Follows NanoClaw philosophy:
- Skills over features - integration is optional via skill
- Keeps base codebase lean
- Users run /add-parallel on their fork for clean code
