- Implement filterErr to detect device-not-found, offline, unauthorized, connection-refused, and multiple-device errors from stderr output - Add ErrDeviceNotFound, ErrDeviceOffline, ErrDeviceUnauthorized, ErrConnectionRefused, ErrMoreThanOneDevice sentinel errors - Remove log.Printf in CaptureSequence (was marked TODO for removal) - Fix ConnString to use local variable instead of mutating value receiver - Update go directive to 1.26.2 - Update README: check implemented features, fix intro typo, add root/keyevent/getevent to supported functions list - Expand filterErr tests for all new error patterns
