Conversation
Install pyenv (pinned to v2.7.1) just below uv, along with the Alpine build dependencies needed to compile CPython from source. This lets the bundled tooling build/install arbitrary Python versions on demand. Only the `pyenv` binary is symlinked onto the PATH; pyenv's shims directory is deliberately left off PATH so its shims don't shadow the system Python that the CLI runs on. bash is required since pyenv and the pyenv-installer are bash scripts.

Bump version to 2.4.1 and document the pyenv addition. The CLI is unchanged; this release exists to publish a Docker image that includes pyenv for on-demand Python version installation.

Adds pyenv to the
socketdev/cliDocker image (just below theuvinstall), so the image can build and install arbitrary Python versions on demand. Tracked in ENG-5094.What changed
v2.7.1(latest stable; the coana reference used the olderv2.6.20), via the pyenv-installer.bash+bzip2-dev,libffi-dev,libxslt-dev,linux-headers,ncurses-dev,openssl-dev,readline-dev,sqlite-dev,xz-dev,zlib-dev).bashis required because pyenv and the pyenv-installer are bash scripts.pyenvbinary is symlinked onto thePATH; pyenv's shims directory is intentionally omitted, so its shims don't shadow the system Python the CLI runs on.2.4.0->2.4.1(+uv.lock, CHANGELOG) so this ships in a published image. No CLI code changes.Verification
Built the image locally (
scripts/build_container.sh pypi-build=local stable=false) and replayed every pyenv action the coana CLI invokes (python-versions-manager.ts) inside the container:which pyenv,pyenv global(system),pyenv install --list(241 versions),pyenv versions --bare,pyenv prefix— all succeed.pyenv install --skip-existing 3.11.14compiles CPython in ~1m18s with no missing-module warnings; the built interpreter runs and imports every stdlib module backed by the added build deps (ssl, ctypes, lzma, bz2, sqlite3, readline, zlib, curses).python3still resolves to the system/usr/local/bin/python3(3.14.5) and.pyenv/shimsis not onPATH.Public Changelog
The
socketdev/cliDocker image now bundles pyenv (v2.7.1) with the build dependencies needed to compile CPython, allowing it to install arbitrary Python versions on demand.
