Extract checkRateLimit and observeStats into their own file (observe.go). Fix the one-tick event-loss bug in observeStats where the retry path used 'unconditional break' instead of fallthrough, causing events collected after a successful retry to be discarded. Add 87 unit tests across 7 files (helpers, metadata, conn, handler, connect, forward, bind) covering all handler modes, error paths, observer/stats integration, and conn wrapper edge cases. handler.go: -43 lines (unused observer import, extracted functions) observe.go: +52 lines (checkRateLimit, observeStats with fallthrough fix) test files: +1959 lines
