Telegram does not echo a sendRichMessage's content back in
reply_to_message (.text/.caption empty, .api_kwargs None), so replies
to rich sends (briefings, the gateway's own rich finals) arrived with
no quotable text and the [Replying to: ...] injection was skipped.
Remember message_id -> text at send time in a best-effort JSON index
(gateway/rich_sent_store.py), and recover it on inbound when text and
caption are both empty. Best-effort and no-throw throughout: any
failure degrades to prior behavior and never breaks a send or message.
Salvaged from #47375 by @x1erra. Dropped the cross-platform run.py
reply-prefix rewrite (out of scope; bloated every reply on every
platform) and scrubbed a docstring reference to an out-of-repo script.
Kept the inbound reply_to logging enrichment used to verify the fix.
