Add decision <model> OpenTelemetry spans for decide, automatic model selection, and tool approvals, with policy-aware model, usage, cost, and failure metadata that distinguishes refusals from request failures.
A decision sits under the operation it runs in, or under the turn when model routing runs before the turn's first step. @vercel/agent-runs adds AgentRun.decision and an optional AgentTelemetry.activeSpan, so a decision nests under a host span inside its operation but not under a host span from another trace, such as a workflow step. (#5349)

Make connection sign-ins countable in traces: each sign-in span names its agent, a failed sign-in records its reason, and a call a connection refused records which connection and why.
agent.approval spans now carry gen_ai.agent.name and agent.name, so a query scoped to one agent no longer drops its sign-in prompts. A sign-in that fails with a reason code such as access_denied records it as agent.connection.authorization.reason; a sign-in that ends any other way, such as one a new message withdrew, records none. A tool call that fails with ConnectionAuthorizationFailedError, including one that never asked anyone to sign in, such as principal_required or sign_in_unavailable in a turn a schedule started, records eve.connection.name and agent.connection.authorization.reason on its execute_tool span. Only reason codes are recorded: a free-text reason or error message stays off the span whatever the trace policy records. (#6078)
