Add conda publish workflow and conda install docs

- New CI workflow publishes the conda package to anaconda.org on push
  of a v<major>.<minor>.<patch> tag, with reviewer-gated upload via a
  GitHub Environment.
- Token flows via the ANACONDA_API_TOKEN env var; anaconda-client is
  installed via pip so the binary lands on PATH in the upload step.
- README documents conda install alongside pip.
- Removed disused linting workflow.
