refactor: build FROM joakimp/pi-devbox:base-pi-only (Option B)

Browse Source 
The pi-only building block now lives in this repo as the internal
base-pi-only tag (produced by opencode-devbox CI from Dockerfile.variant,
INSTALL_OPENCODE=false) instead of opencode-devbox:latest-pi-only — so an
'opencode-devbox' tag never ships without opencode.

- Dockerfile: BASE_IMAGE default joakimp/opencode-devbox:latest-pi-only
  -> joakimp/pi-devbox:base-pi-only.
- Updated README, AGENTS, DOCKER_HUB, docker-compose, CHANGELOG.
- Single source of truth unchanged (opencode-devbox/Dockerfile.variant);
  publish ordering + EXPECTED_PI_VERSION smoke guard unchanged.

## What's inside
pi-devbox is a re-brand of the **opencode-devbox `pi-only` variant** — it `FROM`s
`opencode-devbox:latest-pi-only` and adds no layers of its own. Everything below
is inherited from that single source of truth. The pi-only variant is built with
`INSTALL_OPENCODE=false`, so this image is lean and pi-focused — no opencode.
pi-devbox is a thin re-brand of the **`pi-only` build** — it `FROM`s
`joakimp/pi-devbox:base-pi-only` and adds no layers of its own. That base build
is produced by opencode-devbox's CI (from `opencode-devbox/Dockerfile.variant`
with `INSTALL_OPENCODE=false`, the single source of truth for the pi install +
companions) but is published **into this repo** as the internal building-block
tag `base-pi-only` — *not* under opencode-devbox, so an "opencode-devbox" tag
never ships without opencode. Everything below is inherited from that build,
which is lean and pi-focused — no opencode.
