fix: correct package name (excoveralls) + use branch ref for burrito

Two CI-blocking issues discovered when validating the new GitHub
Actions workflow locally:

1. **ex_coveralls -> excoveralls**: the package on hex.pm is spelled
   'excoveralls' (no underscore). The 404 from hex.pm meant the dep
   couldn't be fetched, so the GitHub Actions workflow would have
   failed at the 'mix deps.get' step on the runner.

2. **burrito ref -> branch**: the SHA 'ef2ff340...' is on the
   'zig-0.16.0' branch but mix deps.get does a shallow fetch that
   doesn't follow branch refs by default. Using 'branch: zig-0.16.0'
   makes mix follow the branch tip directly.

Validated locally:
  - mix deps.get fetches all 30+ deps cleanly
  - mix test -> 107 passed
  - mix test --cover -> 93.52% (threshold enforced)
  - mix coveralls.json -> cover/excoveralls.json (294KB)
  - mix ci -> exit 0 (Credo strict, Dialyzer, xref, format, audit)
