Claude Code 2.1.122 tightens rails, adds Bedrock controls

Hot take: this is a governance release more than a feature release, and that is probably the right tradeoff for an agentic CLI.

• –The strongest user-facing change is the stricter consent gate around risky actions, which should reduce accidental destructive behavior.
• –`ANTHROPIC_BEDROCK_SERVICE_TIER` gives AWS users a clearer way to tune for default, flex, or priority service tiers.
• –The prompt changes suggest Anthropic is pushing more policy into product behavior instead of relying on long static instructions.
• –The new telemetry event is small but useful for operators who want better visibility into mentions and agent activity.
• –The env-var churn around cowork and memory features points to ongoing iteration on how Claude Code stores and uses context.
