chore: rename project from test-esp3 to your-life-in-x

- Update project name in `Cargo.toml` and `Cargo.lock`.
- Update binary name to match the new project name.
- Update `edition` in `Cargo.toml` from 2021 to 2024.
- Add author information to `Cargo.toml`.
- Update `nixpkgs` and `rust-overlay` dependencies in `flake.lock`.

The changes reflect the renaming of the project to better align with its purpose and improve maintainability. The update to the Rust 2024 edition ensures compatibility with the latest language features.
