libtmux.pytest_plugin._reap_test_server

Invoked from the server and TestServer fixture finalizers to guarantee teardown even when the daemon has already exited (kill is a no-op then) and the socket file was left on disk. tmux does not reliably unlink(2) its socket on non-graceful exit, so /tmp/tmux-<uid>/ otherwise accumulates stale entries across test runs.

Conservative: suppresses LibTmuxException / OSError on both the kill and the unlink. A finalizer that raises replaces the real test failure with a cleanup error, and cleanup failures are not actionable (socket already gone, permissions changed, race with a concurrent pytest-xdist worker).
