Multi-stage build: poetry installs the mint into a python:3.12-slim-trixie
stage, then /usr/local and /app are copied onto ghcr.io/coinos/base, the same
way the lightningd image is assembled. Source is cloned from the coinos
nutshell fork at NUTSHELL_REF, and the image runs `mint` directly under tini
instead of `poetry run mint`.

Python 3.12 rather than trixie's 3.13 because coincurve ships no cp313 wheel.
