README.md:12
- The documentation states Python 3.12, but after removing the devcontainer feature, the version is now determined by Ubuntu 24.04's default Python version (likely 3.12.x, but not guaranteed to be 3.12). Consider updating to 'Python 3 (Ubuntu default) with pip' or verify and document the specific version provided by Ubuntu 24.04.
- Python 3.12 with pip

Switch Python setup to use OS precompiled binaries instead of compiling from source.

Benefits:
Note on Node.js: The devcontainer Node feature (ghcr.io/devcontainers/features/node:1 with version "lts") uses prebuilt binaries from upstream and does not compile from source, so no change is needed for Node at this time.
