Updated kr package's version to 1.0.2 in Cargo.toml and Cargo.lock files. Also, fixed the wrong property reference in the GitHub Actions release workflow. From "gitea.actor" to "github.actor" which might have caused incorrect workflow run name in GitHub CI/CD.
In this commit, we've updated the kr package from version 0.1.0 to 1.0.0 in the Cargo.toml file, signifying a milestone update recognizing the project's stability and maturity.
This commit deletes the current codebase and configurations because we're switching to rust. This includes src/index.js, package.json, package-lock.json and .gitignore files. A refactor or rewrite app with updated dependencies and code style will be added afterwards.
