Add a tdc test case that fills the u32 node ID space with 4095 auto-generated handles, then attempts to add a 4096th. On the fixed kernel the 4096th filter is rejected with ENOSPC (exit 2). On the unfixed kernel it silently succeeds with a duplicate handle. The setup pipes the 4095 add commands directly into `tc -b -` inside a single bash -c (matching the existing test id 1234 pattern), avoiding any temp file.
