OpenSandbox 1.1.0-rc.1

Release candidate for the 1.1.0 line and the first end-to-end exercise of the
unified umbrella release pipeline (OSEP-0016). It carries the version bump to
1.1.0-rc.1 across charts and image references; no functional changes are
included. rc releases ship no SDK artifacts — SDK/CLI packages, dependency
ranges, and identity constants move at the 1.1.0 stable bump. Please test the
release mechanics — staging image builds, BOM assembly, and held package
fan-out — and report issues.

Highlights

• First umbrella release candidate on the 1.1.0 line
• Platform version aligned to 1.1.0-rc.1 (charts and image references)

Misc

• release: bump platform version to 1.1.0-rc.1 (#1896)

• Kubernetes: supported range v1.21 – v1.34 (charts declare kubeVersion: ">=1.21.1-0")
