[Feature]: The Feishu plugin's /open-apis/bot/v3/info endpoint is called every minute by Gateway health check. This results in ~43,200 API calls/month, exceeding Feishu's free tier (50,000). #26684
Description
Summary
Problem
The Feishu plugin's /open-apis/bot/v3/info endpoint is called every minute by Gateway health check. This results in ~43,200 API calls/month, exceeding Feishu's free tier (50,000).
Problem to solve
Gateway Health Check (1/min) → probeFeishu() → HTTP GET /open-apis/bot/v3/info
Proposed solution
Add in-memory caching to probeFeishu() with 10-min TTL. Bot info is static, so caching is safe.
