// The long form: Windows runners' temp dir is an 8.3 short path
// (C:\Users\RUNNER~1\...), and this becomes CLAUDE_CONFIG_DIR, which the
// Claude extension watches from inside the IDE server. libuv before 1.53.0
// aborts the whole server on the first event in a short-path watched
// directory (libuv#5010). Only `.native` expands short names.

// port 0: the suite already picks a free port for the IDE server rather than
// colliding with a developer's running instance, and a mock is no different.
