Add `test_subint_forkserver_key_errors_cleanly` — a tn-tier regression guard that pins down the variant-2 reservation contract: the `'subint_forkserver'` key in `_spawn._methods` MUST raise `NotImplementedError` today, not silently dispatch to `main_thread_forkserver_proc`. The transient alias-state existed briefly during the rename (commit `57dae0e4`'s "Split forkserver backend into variant 1/2 mods" landed the alias; `5e83881f` flipped it to the stub). Without a guard, a future refactor could easily re-collapse the two keys back to a single coro and silently break the variant-1 / variant-2 contract. Also asserts the stub's error msg surfaces the two pointers an operator hitting it actually needs: - `'main_thread_forkserver'` — the working backend they prolly meant, - `'msgspec#1026'` — the upstream blocker that has to land before variant-2 can ship.
