Rate limits

Every answer carries RateLimit-Limit, RateLimit-Remaining and RateLimit-Reset, so a client can pace itself rather than discovering the ceiling by hitting it. The limits are per account, not per key, and are on /api/v1/me.

Over the limit is 429 with Retry-After in seconds. Refused calls count against the limit as well, so retrying immediately makes it worse — wait for the reset. Webhook deliveries don't count.
