Addresses PERFORMANCE-FINDINGS #1, #4, #6 (and #2 in creategroup flow): - Add app/telnet-pool.js: pool of N connections (config.telnet.poolSize, default 4) with wait-queue, lazy reconnect, and respawn on dead socket. - Remove module-level new Telnet() singleton and startup socket dump from app/routes/index.js; switch all mutating endpoints to telnetPool.send(). - Set telnet debug:false; use config.telnet.timeout (default 5s) instead of hardcoded 30000. - Add telnet.poolSize to config/prosody-muc-rest.js. - await doesMucExist in /creategroup so the existence check is no longer dead.
