Moonshot/Kimi requires reasoning_content on all assistant tool-call messages
when thinking is enabled. After LCM compaction, cross-model fallback, or
session repair, the replayed history may be missing this field, causing a
400 error from the Moonshot API.
Backfill an empty string to satisfy the API schema contract without
fabricating semantic reasoning content. Follows the same provider-owned
backfill pattern already used by Kimi Coding (extensions/kimi-coding/stream.ts)
and DeepSeek V4 (provider-stream-shared.ts).
