v0.19.0

New Features

• pool exhaustion handling: cooldowns now derive from the upstream Retry-After and x-ratelimit-reset hints, exhaustion is detected when no pool member is healthy, and the exhausted and recovered notices fire once on the edge via a server-side recovery monitor #49 @nnemirovsky
• opt-in per-pool auth_reset_target that resets the agent's auth on the exhausted-to-recovered edge, settable from CLI, REST, and Telegram #49 @nnemirovsky
