… attempt Follow-up to #289: resolve_attempt_tcp::cancel() has the same shared_from_this() race as resolve_attempt_udp::cancel() when the io thread drops the last owner while cancel_all_registered() is running.

Fixes the intermittent
std::bad_weak_ptr→std::terminate/SIGABRTon inlet destruction reported in #220:resolve_attempt_udp::cancel()callsshared_from_this()on an attempt that has no live shared owner, and the exception skips the watchdogjoin(), leaving~inlet_connectionto destroy a joinablestd::thread. #220 was closed by #246, but #246 only fixes the outlet-side garbage-sample bug (consumer_queue.h/tcp_server.cpp) and never touches the inlet resolver-cancellation path, so the crash still reproduces on current main.Those changes have been suggested by Claude (Fable) following digging in a CI failure on mne-tools/mne-lsl#565. This changes are outside my expertise and comfort zone, thus up to you to merge or iterate on those changes.
