The Dockerfile has been refactored to a multi-stage build, allowing the `whisper.cpp` CLI binary to be compiled and embedded within the application's runtime image. This enables word-by-word highlighting functionality when deployed via Docker. The `README.md` has been updated to include installation and configuration instructions for `whisper.cpp` when running locally. Additionally, the `WHISPER_CPP_BIN` environment variable has been added to `template.env` and the package version has been bumped to v1.1.0.
