Docker support (#50)

* feat: add Dockerfile

* feat: add Docker release workflow docs

* fix: pin home crate to <0.5.12 to avoid edition2024 requirement

The home v0.5.12 crate was published requiring Rust edition 2024,
which is not stabilized in stable Rust. Pin to v0.5.11 to maintain
compatibility with stable Rust toolchains.
