Windows CI is ~4min vs ~2min for unix and frequently blocks PR merges. Split the test matrix: ubuntu+macOS remain required (gate the ci summary job), Windows runs separately as visible-but-non-blocking. No branch protection rule changes needed; ci summary job's needs array already excludes test-windows.

Atlas review: no further findings from my side. The workflow split is appropriately narrow: unix stays in the blocking |

Summary
testjob:[ubuntu-latest, macos-latest]-- required, gates thecisummarytest-windowsjob: runs in parallel, visible on PR but does not block mergesWhy
Windows CI takes ~4min vs ~2min for unix and has been blocking PR merges (e.g. grip#484 waited 30+ minutes on a single Windows leg). Windows failures should be visible but not gate merges.
Closes #486.
