Claude Managed Agents adds scheduled runs and environment variable storage

Claude Managed Agents 新增定时运行和环境变量存储功能

Claude Managed Agents added cron-based scheduled runs and vaults environment variable storage in public beta, with real secrets attached only at the network boundary so agents cannot read them directly.

Why it matters: HKR-H/K/R all pass: this first-party Claude update adds concrete agent-ops mechanics with cron scheduling and vault-bound secrets. It is not a model release, so it stays in the lower good-quality band.
