Merge branch 'main' into canary

Resolve conflicts in docker.ts and domain.ts: canary already contains
a superset of main's hotfix cherry-picks (isDockerDesktop, isolated
network label pinning), just refactored/reformatted, so both sides
kept canary's version.

Also fix hotfix-cherry-pick.yml to sync each cherry-pick back into
canary immediately, so canary and main share history for that change
and the next canary->main release PR doesn't re-conflict on it.
