# node-build — install + build an npm/bun project (999_testing).
#
# A COMPOSITE ACTION (not a reusable workflow — Forgejo 11 does not support
# job-level `uses:`/workflow_call; composite actions referenced by full URL are
# the working cross-repo reuse mechanism). Downstream repos call it at STEP level:
#
#   jobs:
#     build:
#       runs-on: docker
#       container: { image: foundation-ci:latest }
#       steps:
#         - uses: actions/checkout@v4
#         - uses: https://forge.olsitec.net/olsitec/foundation/actions/node-build@master
#           with: { package-manager: bun, build: "bun run build" }
#
# Covers the non-Docker candidate shapes: npm package built with npm (olsicrypto),
# bun package built with bun (document-engine), no-artifact/versioned (olsitrack/api,
# empty `build`). The caller must `actions/checkout` first and run in foundation-ci.
