fix: Add README.md and LICENSE to org .github repo

[chitcommit]

Problem

Workflow Documentation Check fails because required files are missing: README.md, LICENSE.

Fix

1. Add a README.md describing the CHITTYOS org-level GitHub configuration
2. Add a LICENSE file (MIT, matching other ecosystem repos)

These are standard compliance requirements per ChittyCanon.
