Add bounds checking when accessing the softirq_name array using the vector value from kernel trace data. The vector field from the osnoise:softirq_noise event is used directly as an array index without validation, which could cause an out-of-bounds read if the kernel provides an unexpected vector value. The softirq_name array contains 10 elements corresponding to the standard Linux softirq vectors. While the kernel should only provide valid vector values in the range 0-9, defensive programming requires validating untrusted input before using it as an array index. If an out-of-range vector is encountered, display the word UNKNOWN instead of attempting to read beyond the array bounds.
