Summary

CI Docker image builds fail due to Anaconda package repository rate limits (Your usage of the Anaconda package repository exceeds our rate limits).

Switch from Miniconda to Miniforge, which uses conda-forge as its default channel and avoids Anaconda's default repository entirely. Miniforge is otherwise fully compatible.

  • .ci/docker/common/install_conda.sh: Download from github.com/conda-forge/miniforge/releases instead of repo.anaconda.com/miniconda
  • .ci/docker/build.sh: MINICONDA_VERSION=23.10.0-1 → MINIFORGE_VERSION=24.11.3-0
  • .ci/docker/ubuntu/Dockerfile: ARG MINICONDA_VERSION → ARG MINIFORGE_VERSION

Test plan

Verified both Miniforge download URLs (x86_64 and aarch64) resolve correctly. The rest of the conda environment setup (Python version selection, conda-env-ci.txt, pip dependencies, libstdc++ hack) is unchanged.

Switch CI Docker image from Miniconda to Miniforge to avoid Anaconda …
4816246 
…rate limits

Replace Miniconda (which uses Anaconda's rate-limited default package
repository) with Miniforge (which uses conda-forge). This resolves CI
Docker image build failures caused by Anaconda ToS rate limits.
