Pulumi v3.239.0 adds structured JSON output for `pulumi import`, introduces stack introspection commands (`pulumi stack get`, webhook management, deployment listing), and fixes silent batch encryption/decryption errors.

Why it matters: CLI improvements reduce scripting friction for stack management and automation. Batch encryption fix surfaces previously silent errors. Standard feature release; evaluate new commands, deploy in next maintenance window.
