refactor: FROM opencode-devbox:latest-pi-only (lean, no opencode)
Re-point the re-brand at the new pi-only variant instead of with-pi, so pi-devbox stays a lean pi-focused image (no opencode) while the pi install logic still lives in one place upstream. This keeps pi-devbox meaningfully distinct from opencode-devbox:latest-with-pi. - Dockerfile: BASE_IMAGE default -> joakimp/opencode-devbox:latest-pi-only. - smoke-test.sh: size threshold 2900 -> 2750 MB (pi-only = with-pi minus opencode's ~145 MB binary). - Docs (README/AGENTS/DOCKER_HUB/CHANGELOG/docker-compose): drop the 'also contains opencode' notes; describe pi-only basis and the distinction from with-pi. Publish ordering unchanged: release opencode-devbox first so latest-pi-only carries the target pi version, then tag here (smoke asserts pi --version).
