Reusable test workflow (Track Q): .github/workflows/test.yml (workflow_call) runs install, node --check over server/ and scripts/, the tests, openvibe-contracts-check for the named service and optional extra commands, with the Node version production runs; repositories call it pinned to a commit instead of carrying copies

++name: test
++# The test job every OpenVibers Node service repository runs (roadmap Track Q): one definition,
++# called from each repository's CI and pinned to a commit of this repo, so the steps, the Node
++# version and the checks do not drift between 30 copies.
++#
++#   jobs:
++#     test:
++#       uses: OpenVibers/OpenVibe.Shared/.github/workflows/test.yml@<sha>

++# Steps, in order:
++#   install      `install` (default npm ci) with the npm cache
++#   syntax       node --check on every .js/.cjs/.mjs file under `syntax-dirs` (default: server
++#                scripts), node_modules excluded; a directory that does not exist is skipped
++#   test         `test` (default npm test)
++#   contracts    openvibe-contracts-check --service <contracts-service> --src <contracts-src>, when
++#                contracts-service is set: the code's capability and event use against the release
++#   extra        `extra`, when set: any further commands, one per line (e.g. a budget check)
