Subject: [PATCH] chore: CI setup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors the standard beam-bots CI scaffolding from bb_servo_feetech /
bb_liveview / etc.:

- `.github/workflows/ci.yml` — delegates to the
  `beam-bots/.github/.github/workflows/elixir-ci.yml` reusable workflow,
  pinned to the same commit (61ed48a) the rest of the ecosystem uses.
  Enables docs deploy and hex release on tagged versions.
- `.github/dependabot.yml` — weekly Mix and GitHub Actions updates,
  with dev-dependencies grouped into a single PR.
- `renovate.json` + `.license` sidecar — asdf-managed tool version
  updates on a monthly schedule.
- `.tool-versions` — pins erlang 28.2, elixir 1.19.4, pipx 1.8.0.
