Subject: [PATCH] Add Dev Container and Ona automations

Configure a reproducible development environment for the pnpm monorepo:

- Dev Container based on the javascript-node:22 image, with shellcheck and
  shfmt installed (required by the server test suite) and pnpm pinned to the
  version in .tool-versions.
- Ona automations for install, compile, test, and lint, mirroring the CI
  workflow.
