feat: packages worker temporal scaffold

[epipav]

Note

Medium Risk
Introduces Temporal schedules and a new worker runtime path for packages-worker; production impact is limited while workflows are placeholders, but misconfigured namespace/task queue could prevent jobs from running.

Overview
packages-worker stops being an idle process with file-based health probes and becomes a Temporal worker via @crowd/archetype-worker, aligned with other crowd workers.

On startup it registers a daily schedule (npm-registry-ingest, cron 15 3 * * *) that runs a placeholder npmHello workflow calling sayHiNpm on the packages-worker task queue—scaffolding for future npm registry ingest, not real ingest yet.

Configuration and deploy wire a dedicated packages Temporal namespace (CROWD_PACKAGES_TEMPORAL_NAMESPACE in local env and compose), set CROWD_TEMPORAL_TASKQUEUE / namespace in packages-worker scripts and Docker Compose, and add Temporal client/workflow plus archetype dependencies. The Docker image moves to bookworm-slim, installs build deps via apt, copies only archetypes/libs/packages_worker, uses a dockerignore, and adds a builder env file for the OCI image.

The github-repos-enricher path is unchanged in behavior aside from a tighter worker loop (while (nextIdx < validUrls.length) instead of unbounded while (true)) and minor formatting/logging tweaks.

Pull request overview

This PR converts packages_worker from an idle/health-probe process into a Temporal-backed ServiceWorker, scaffolding an initial (placeholder) npm ingest workflow + activity + cron schedule and wiring a dedicated Temporal namespace via CROWD_PACKAGES_TEMPORAL_NAMESPACE. It also updates build/deploy assets (Dockerfile, compose service env, builder definition) and applies non-functional formatting changes in the GitHub repos enricher.

Changes:

• Replace packages-worker entrypoint with ServiceWorker Temporal worker startup and register an npm-registry-ingest Temporal Schedule.
• Add minimal Temporal workflow/activity scaffold for npm (npmHello + sayHiNpm) and export wiring for worker registration.
• Update Docker/build + compose/env plumbing for the packages worker (namespace/task queue env, Dockerfile changes, builder env file); minor formatting-only enricher edits.
