Also rewrite the stale test_lean_server_start_failure test: start() was redesigned to a pure env-capability check (no Popen worker); spawn-failure recording now happens in probe()/elaborate(), so the test patches both the LSP Popen and the single-shot subprocess.run paths and asserts via probe/available.
