nx_fnres_offset_probe.nx

nx_fnres_offset_probe.nx -- proves the FNRES offset desync is fixed (debt 1785521219). THE DEFECT: nx_autofix_auto's fn_failing clamped the parsed name to 23 bytes, then located the `passed` and `total` fields at `r + 6 + nl + 1` -- i.e. from the CLAMPED length. For any function name longer than 23 characters that offset lands INSIDE the name, the digit scan hits letters and bails, and `passed` stays 0. The tool then reports ZERO TESTS PASSED for a function that passed all of them -- a wrong NUMBER, not a crash, in a tool that judges fixes by that number. THIS PROBE USES A 30-CHAR NAME (over the 23 clamp) so it exercises exactly the broken path. With the old code T2 reads passed=0; with the fix it reads passed=7. expect_exit: 0 license_tier: ORIGINAL
