fix(telegram): deliver reasoning lane under /reasoning on

wendy-chsy · claude · wendy-chsy · commit a2f9d696ba09 · 2026-06-20T01:10:46.000+08:00
Reasoning blocks from the reply pipeline carry isReasoning=true and are suppressed by normalizeDeliveryPayload via shouldSuppressReasoningPayload. Deliver them through the reasoning lane before the normalizer runs, so thinking persists as messages when /reasoning on is active (/reasoning stream worked because ephemeral streaming bypassed this path).
