Configured the `Cargo.toml` to automatically strip symbols, optimize for size, enable Link Time Optimization (LTO), and set codegen-units to 1 for the release profile. This significantly reduces the size and improves the performance of the resulting binary.
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.
