FdSet.Set, Clear, and IsSet do not validate the fd parameter before indexing into fds.Bits, causing a runtime panic when fd >= FD_SETSIZE (1024) or fd < 0.

This adds bounds checks consistent with the CPUSet helpers in affinity_linux.go, which already guard against out-of-range indices via cpuBitsIndex checks.

Set and Clear silently return on out-of-range fd (matching CPUSet.Set/Clear behavior). IsSet returns false.
