fix(feishu): enrich reply context for card and file replies (#2144)

* fix(feishu): enrich reply context for card and file replies * refactor(feishu): extract reply functions to feishu_reply.go - Move reply-related functions to new feishu_reply.go - Move corresponding tests to feishu_reply_test.go - Extract magic number 600 to maxReplyContextLen constant - Unify replyTargetID/replyTargetFromMessage (prefer parent_id, fallback root_id) - Add source comment for containsFeishuUpgradePlaceholder * fix(feishu): skip API fallback for non-thread messages, prepend replied media refs - resolveReplyTargetMessageID: only call fetchMessageByID fallback when ThreadId is set, avoiding unnecessary API calls for non-reply messages - prependReplyContext: prepend replied media refs before current media refs to maintain correct ordering * fix(feishu): add message cache for fetchMessageByID to avoid repeated downloads - Add messageCache (sync.Map) to FeishuChannel struct - Cache fetched messages with 30s TTL to avoid re-downloading attachments when multiple users reply to the same parent message in a thread - Cleanup expired entries on read access (no background goroutine needed) * fix(feishu): early-return for non-reply messages, add cache and fetchMessageByID comment * fix: remove duplicate test and fix gci import order * fix(feishu): remove duplicate prependReplyContext call
