Add Peer Production License (copyfarleft)

Apply the Peer Production License to the macha-autonomous codebase.

The PPL is a copyfarleft license that restricts commercial use to
worker-owned cooperatives and collectives, preventing exploitation by
for-profit companies that use wage labor.

This aligns with the commons-based peer production model and ensures
that the fruits of this work benefit worker-owned entities and the
broader commons, not extractive capitalist enterprises.

Key changes:
- Add LICENSE file with full Peer Production License text
- Update README.md with license information and usage guidelines
- Clarify that worker cooperatives can use commercially
- Restrict for-profit wage-labor companies from commercial use
