Managed-settings failures now include a machine-readable reason

What

• Org login/managed-settings validation failures now carry a machine-readable reason (for example managed_settings_invalid or org_pin_api_key_conflict) and a policyUnreadable flag, in addition to the existing human-readable message.
• When managed settings are unreadable or invalid, or a policy refusal state exists, Claude Code now sends a dedicated telemetry export (using OTel, a tracing/telemetry standard) that force-flushes with a timeout, rather than relying on general telemetry.

Why The structured reason and flag let tooling distinguish specific managed-settings failure causes instead of parsing free text, and the dedicated telemetry export makes it more likely that failure data reaches the server before the process exits.
