Pulumi v3.245.0 updates dependencies, adds CLI progress UI features, fixes several bugs, and introduces two breaking changes: renaming `stack init` to `new` and altering the Go SDK plugin API.

Why it matters: Breaking commands (`pulumi stack init` → `new`) require command‑line adjustments; removing "name" from Go SDK plugin loading mandates code updates. All changes apply in version v3.245.0 released 2026-06-04.
