v0.1.41

Added

• New codewhale preset — supervise Hmbown/CodeWhale (DeepSeek terminal agent) via codewhale exec --auto --output-format stream-json. agent-runner init --preset codewhale.
• New built-in codewhale_error_detector plugin — emits agent_usage_recorded (model + token counts) from codewhale's stream-json output. Transient-error classification is best-effort (mappable buckets only); auth failures surface via the existing monitor oauth_fail detector.
