Maintenance: repo hygiene checklist

[DatanoiseTV]

This is an automated maintenance task.

The following files are missing from this repo:

• LICENSE — Cargo.toml declares MIT OR Apache-2.0 but no LICENSE file is present at the repo root
• .github/workflows/ — no CI pipeline configured (consider a basic cargo build/cargo test workflow)
• .github/dependabot.yml — no automated dependency updates configured (a draft PR is on its way via a separate automated run)
