RepeatOpenDoesNotIssueSecondHead failed flakily in the ladybug repo CI (headCount()==0) under `ctest -j10`. The vendored httplib enables SO_REUSEPORT by default on Linux, which lets multiple sockets bind the same port and load-balances connections between them. ctest runs each gtest case in its own process, so two concurrent test processes both successfully bound 127.0.0.1:18123 and the kernel routed some requests to the other process's server - the HEAD-count assertion then observed requests that never reached the server it was checking (reproduced locally: two concurrent processes both bound 18123, and the failing process saw headCount 0 or 2). Override the server socket options to set only SO_REUSEADDR so a second bind of the same port fails with EADDRINUSE and the existing port scan falls through to a genuinely free port. 20 consecutive `ctest -j10` runs pass with this change; without it ~25% of runs failed.
