# Report this session's cumulative cost to AI Maestro so the agent's "API Cost"
# metric reflects real usage. Best-effort, backgrounded, never blocks the render.
# Only PATCH when the cost has GROWN (monotonic): avoids spamming the API every
# render and avoids the value dipping to ~0 when a new session starts. (Lifetime
# accumulation across sessions is a later OTLP concern.)
