Add INSTALL_PI build arg for pi as second harness

Optional integration of pi-coding-agent alongside opencode in the same
container. Both harnesses share the mempalace install and palace path —
wing/diary entries are mutually visible.

Build:
  --build-arg INSTALL_PI=true              # opt-in
  --build-arg PI_VERSION=0.73.1            # pin a version (default: latest)
  --build-arg INSTALL_OPENCODE=false       # build pi-only image

Dockerfile:
  • New INSTALL_PI block: npm install -g @mariozechner/pi-coding-agent
    + git-clones pi-toolkit and pi-extensions to /opt/.
  • Existing opencode install gated behind new INSTALL_OPENCODE arg
    (default true; existing builds unaffected).
  • mkdir adds ~/.pi/agent/extensions for the named volume mount root.
  • CMD changed from ['opencode'] to ['bash', '-l']. compose run --rm
    devbox now drops to a login shell so users pick the harness; pass
    'opencode' or 'pi' explicitly to launch directly. compose exec
    workflows are unaffected (bypass entrypoint+CMD).

entrypoint.sh:
  • Adds ~/.pi to volume ownership loop.

entrypoint-user.sh:
  • New 'pi: deploy toolkit + extensions + mempalace bridge' block runs
    pi-toolkit/install.sh, pi-extensions/install.sh, settings.json
    template bootstrap, then symlinks the mempalace.ts bridge directly.
    Order: toolkit before extensions before bridge. mempalace-toolkit's
    full install.sh is intentionally NOT called (its install_skill
    would race with skillset auto-deploy --prune-stale).

docker-compose.yml:
  • New devbox-pi-config named volume mounted at /home/developer/.pi.
    Persists user toggles (/ext-disabled extensions) and settings.json
    edits across container recreate. Mirrors devbox-opencode-config
    pattern from v1.14.33.

scripts/smoke-test.sh:
  • New --variant with-pi (threshold 2700 MB) and --variant omos-with-pi
    (3400 MB).
  • Pi assertions gated on `command -v pi`: version, /opt/pi-toolkit
    clone HEAD, /opt/pi-extensions clone HEAD, deployed keybindings
    symlink, ≥4 extension symlinks, mempalace.ts bridge symlink,
    settings.json bootstrap.
  • Pi state assertions use docker exec from the host (not 'run'),
    since the container has no docker CLI.
  • opencode core test now gated on INSTALL_OPENCODE presence.

scripts/generate-dockerhub-md.py:
  • SECTION_RULES adds 'pi (alternative/complementary harness)': drop.
    Section stays in README; dropped from DOCKER_HUB.md to keep under
    the 25 kB Docker Hub limit.

Docs:
  • README adds full 'pi (alternative/complementary harness)' section.
  • AGENTS.md codifies pi install contract, deploy ordering, named
    volume rationale, and CMD change.
  • CHANGELOG.md gets an Unreleased entry.
  • .env.example documents new build args.
  • docker-compose.yml example args block updated.

Verification (local builds on arm64):
  • Default (INSTALL_PI=false): 1871 MB, all assertions pass — no
    regression.
  • INSTALL_PI=true: 2110 MB (within 2700 threshold), 37 assertions
    pass including pi version, all 7 extensions deployed (6 from
    pi-extensions + mempalace.ts bridge), settings.json bootstrap.

Not yet:
  • CI workflow updates to add -with-pi tag variants. Deferred until
    local path stabilizes through user testing.
  • pi-devbox separate repo for fully stripped pi-only image. Phase 2.

## pi (alternative/complementary harness)
[pi](https://github.com/mariozechner/pi-coding-agent) is a lightweight TUI coding-agent that can run alongside opencode in the same container. Both harnesses share the mempalace install and palace data — wing/diary entries created by one are visible to the other.
### Build
```bash
docker compose build --build-arg INSTALL_PI=true
# Or: pin a pi version
docker compose build --build-arg INSTALL_PI=true --build-arg PI_VERSION=0.73.0
# Or: pi-only image (no opencode, smaller)
docker compose build --build-arg INSTALL_PI=true --build-arg INSTALL_OPENCODE=false
```
### Run
The default `compose run --rm devbox` invocation drops to a login bash so you can choose:
```bash
docker compose run --rm devbox # bash, then `pi` or `opencode` or `aws sso login`
docker compose run --rm devbox pi # launch pi directly
docker compose run --rm devbox opencode
```
For an attached `compose up -d` container, both harnesses are reachable via `compose exec`:
```bash
docker compose exec -u developer devbox pi
docker compose exec -u developer devbox opencode
docker compose exec -u developer devbox bash
```
### What gets installed
- **`pi` CLI** — npm-installed globally at build time. Version pinned by `PI_VERSION`.
- **pi-toolkit** — keybindings.json (mosh/tmux newline fixes), pi-env.zsh (AWS env loader), settings.json template. Cloned to `/opt/pi-toolkit`; deployed to `~/.pi/agent/` on first container start.
- **pi-extensions** — 6 extensions: `confirm-destructive`, `ext-toggle` (`/ext` slash command), `git-checkpoint`, `notify`, `ssh-controlmaster`, `todo`. Cloned to `/opt/pi-extensions`; symlinked into `~/.pi/agent/extensions/`.
- **mempalace bridge** — `mempalace.ts` extension symlinked from the cloned mempalace-toolkit. Provides pi's MCP tools for palace search/diary/kg.
### Persistence
`~/.pi/` is mounted on the `devbox-pi-config` named volume. User toggles via `/ext`, edits to `~/.pi/agent/settings.json`, and any pi state survive container recreate. `pi update` writes to the npm global prefix which is *not* on a volume — image rebuild is the upgrade path.
### Configuration
The entrypoint copies `pi-toolkit/settings.example.json` to `~/.pi/agent/settings.json` on first start. Edit it to set provider/model:
```bash
docker compose exec -u developer devbox $EDITOR ~/.pi/agent/settings.json
```
The AWS env loader (`pi-env.zsh`) reads `~/.config/pi/.env` if you bind-mount one; otherwise pi uses container env vars passed via `.env`.
