## What this PR does Overrides the seaweedfs master anti-affinity in the package values from a hard `requiredDuringSchedulingIgnoredDuringExecution` hostname term to a strong preference (`preferredDuringSchedulingIgnoredDuringExecution`, weight 100). The selector and topologyKey are unchanged. The vendored subchart pins the master to a hard hostname anti-affinity — its own comment notes that emptying it is what allows single-node deployment. With the master StatefulSet at three replicas, the surplus master Pods stay Pending forever on clusters with fewer than three nodes, so `helm install --wait` never returns and the S3 stack never comes up. Softening to a strong preference keeps the masters spread across distinct nodes whenever the cluster has them (the scheduler only co-locates when there is no alternative — exactly the small-cluster case), while letting single- and dual-node clusters bring the master up. This mirrors the posture already applied to the s3 component in the same values file. A helm-unittest pins the softened term (asserts the hard term is gone and the preferred term carries the right weight, topologyKey, and component selector) so a future subchart bump cannot silently re-harden it. ### Screenshots N/A — no UI changes. ### Release note ```release-note fix(seaweedfs): soften the master anti-affinity to a preference so the S3 stack installs on clusters with fewer than three nodes ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * SeaweedFS master pods now use a softer scheduling preference for hostname separation, improving deployment success on smaller clusters. * **Tests** * Added a Helm chart validation to confirm the anti-affinity behavior is now expressed as a weighted preference (not a hard requirement), including the expected selector and topology key. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
