Version 4.0.0

Breaking Changes

@copilot It looks like this upgrade of setup-miniconda from version 3 to version 4 has broken our CI build pipeline for conda packaging. Can you take a look at the failing CI build actions workflow and figure out what we need to change about our packaging for Anaconda? We currently run conda build but it seems like that CLI has changed with version 4.

I investigated the failing workflow run and confirmed the break: after setup-miniconda@v4, conda build was unavailable because conda-build was being installed into the active test env instead of base (where the conda CLI/plugin lives). I fixed this in commit f995482 by changing the build step to install with conda install -n base -y conda-build, which restores the conda build command in CI.
