Bohan Jiang 5eba94ee25 feat(lark): inbound context enrichment — post / merge_forward / quoted-reply (MUL-2951) (#3724)
Expand an inbound Lark bot message's body before dispatch with the context
a user explicitly attached, so the agent sees a semantically complete
conversation instead of a bare "@bot 总结一下".

- post: flatten rich-text (title + paragraphs, links, @-mentions) to plain
  text synchronously in the decoder.
- merge_forward: inline the forwarded transcript via a single GetMessage —
  GET /open-apis/im/v1/messages/{id} returns the forward sentinel plus the
  bundled children. (The issue's container_id_type=merge_forward query is
  undocumented; this avoids it and also handles a forwarded quoted parent.)
- quoted reply: prepend the parent_id message as a <quoted_message> block;
  a parent that is itself a forward nests a <forwarded_messages> block.
- new InboundEnricher runs in the WS connector between decode and emit,
  bounded by EnrichTimeout and degrading to "[unable to fetch]" placeholders
  so it never blocks the ~3s long-conn ACK budget.

/issue stays parseable on a quote-reply by parsing the command from the
user's own text (CommandBody) rather than the enriched body.

Short-window debounce batching (issue item #4) is tracked as a follow-up.
