What does this PR do?

Adds the v1.1.0 release notes section to CHANGELOG.md, ahead of the upstream v1.1.0 release.

Curated from the PRs merged for this cycle (associated with the v1.1.x milestone):

Features

• Configurable pod scheduling (podAffinity / podAntiAffinity / topologySpreadConstraints) for workspaces and operator-managed jobs #1723

Bug Fixes & Improvements

• Prevent the shared claim-devworkspace PVC from getting stuck Terminating on concurrent workspace cleanup #1725
• Allow the OpenShift console namespace through the default workspace NetworkPolicy (WebTerminal) #1724
• Preserve deny-all NetworkPolicy config and stop mutating/sharing default rules #1721
• Default operator-managed init container imagePullPolicy to IfNotPresent #1692

Notes for reviewers

• This is documentation only — the release scripts (make-release.sh) do not read CHANGELOG.md.
• The 1.1.x release branch was already cut (prerelease) before this changelog, so 1.1.x will not auto-inherit these notes. Per decision, the changelog is targeted at main only. Please confirm the out-of-order sequence (branch cut before changelog) is acceptable.
• Minor entries were intentionally omitted from the curated list: internal refactor #1719 and dependency bumps (#1726, #1731).

Summary by CodeRabbit

• New Features
  • Added configurable pod affinity, anti-affinity, and topology spread constraints for workspace and operator-managed job pods, with global settings and per-workspace overrides.
• Bug Fixes
  • Fixed shared PVC deletion races on Kubernetes 1.33 and newer.
  • Allowed the OpenShift console namespace through the default workspace NetworkPolicy.
  • Preserved explicitly empty NetworkPolicy ingress and egress lists, and prevented default rules from being changed or shared.
  • Set the default image pull policy for operator-managed init containers to IfNotPresent; user and devfile container policies remain unchanged.

Merge Risk: Low · up to c1464

This is a documentation-only change. The changelog example could mislead users who copy the spread configuration for workspaces that share a ReadWriteOnce volume. Adding a caveat to the example is a small follow-up and does not block the merge.

Warn against spreading pods that share a ReadWriteOnce PVC.

For per-user storage, workspaces in a namespace share a PVC. The default access mode is ReadWriteOnce. (raw.githubusercontent.com)

This selector can cause the scheduler to place a second workspace on another node. With a single-node volume, that workspace can then fail to attach the PVC and remain unavailable. (v1-33.docs.kubernetes.io)

State that this example requires independent volumes or storage that supports multi-node access. Alternatively, use an example safe for shared ReadWriteOnce PVCs.
