healthchecks Fix ENV instructions to expand $VAR references at set time using the current env state, preventing self-referencing values like PATH=/opt/venv/bin:$PATH from producing recursive expansions. Remove expandEnv from shellPrefix to avoid double expansion. Fetch sandbox environment variables via `env` before recipe execution so ENV steps resolve against actual runtime values from the base template image. Replace hardcoded healthcheck timing with a Dockerfile-like flag parser supporting --interval, --timeout, --start-period, and --retries. Add start-period grace window and bounded retry counting to waitForHealthcheck. Add python-interpreter-v0-beta recipe and healthcheck files.
