Confirm public contribution policy and licensing

Nobody has claimed this yet.

This public non-fork repository has 25 commits and its README says MIT, but it has no LICENSE file, CONTRIBUTING.md, SECURITY.md, CI workflow, or branch protection. The README says the CLI source lives in https://github.com/manaflow-ai/manaflow/tree/main/packages/cloudrouter, which may make this repository a documentation or skill mirror rather than the canonical source.\n\nPlease confirm whether this repository accepts external pull requests. If it does, add the canonical license file, contributor and security guidance, CI, and branch protection, then decide whether CLA Assistant v3 is legally required. If it does not, document the canonical source and mark this repository as a read-only mirror.\n\nNo CLA workflow is proposed until this ownership and legal decision is recorded.

Please name at least two maintainers who will review security and CLA changes.

Start by checking the README and the referenced packages/cloudrouter path to confirm whether this repository is canonical or a mirror. Then resolve the external-contribution policy with maintainers before changing repository governance. Done means the ownership decision, review maintainers, legal CLA decision, and either the requested guidance and controls or read-only mirror status are recorded.
