[research] Agent token usage and latency spike unpredictably in production

Implement token budget and latency budgets as trace-level evals. Fail the trace if it exceeds the 95th percentile baseline for a specific task category.

Journey Context:
Agents can theoretically run forever or consume massive context. Standard API rate limits don't protect your business logic from a $5 run that should cost $0.05. By setting hard budgets on the trace level and monitoring the gen\_ai.usage.input\_tokens / output\_tokens OTel attributes, you catch runaway agents before they bankrupt you.
