Add `pull_policy: build` to every agent service emitted by the generator
that shares `docker/agents/Dockerfile` as its build context. Without it,
`docker compose up -d --force-recreate agents-<name>` reuses the cached
`disinto/agents:latest` image and silently keeps running stale
`docker/agents/entrypoint.sh` code even after the repo is updated. This
masked PR #864 (and likely earlier merges) — the fix landed on disk but
never reached the container.
#853 already paired `build:` with `image:` on hired-agent stanzas, which
was enough for first-time ups but not for re-ups. `pull_policy: build`
tells Compose to rebuild the image on every up; BuildKit's layer cache
makes the no-change case near-instant, and the change case picks up the
new source automatically. This covers:
- TOML-driven `agents-<name>` hired via `disinto hire-an-agent` — primary
target of the issue.
- Legacy `agents-llama` and `agents-llama-all` stanzas — same Dockerfile,
same staleness problem.
`bin/disinto up` already passed `--build`, so operators on the supported
UX path were already covered; this closes the gap for the direct
`docker compose` path the issue explicitly names in its acceptance.
Regression test added to `tests/lib-generators.bats` to pin the directive
alongside the existing #853 build/image invariants.
