v0.2.0

Project renamed from KyoSabi to Watari. No functional changes to the app itself — this release is naming, docs, and CI groundwork.

Changed

• 🏷️ Renamed KyoSabi → Watari, throughout the crate, Docker service/volume names, and all docs/comments (kyosabi.md → watari.md).
• 📄 README rewrite: project description, badges (crates.io, license, top-language, CI), and WIP disclaimer.
• 🎨 HTML templates reformatted to consistent 2-space indentation.

CI

• ✅ Added GitHub Actions pipeline (rust.yml): build + test, clippy lints, and cargo fmt --check on push/PR to main.
