Gud Boi cbdf1eb6db Guard `subint_forkserver` stub against re-alias
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.
