Rename `tests/spawn/test_subint_forkserver.py` →
`test_main_thread_forkserver.py` and migrate its imports +
internal refs to the new canonical names:
- `fork_from_worker_thread`, `wait_child` → from
`tractor.spawn._main_thread_forkserver`.
- `run_subint_in_worker_thread` → still from `_subint_forkserver`
(variant-2 primitive).
- Module docstring + tier-3 fixture + the `*_spawn_basic` test fn
renamed for variant-1-honesty.
- Orphan-harness subprocess argv flipped from `'subint_forkserver'`
→ `'main_thread_forkserver'`.
`ai/conc-anal/subint_fork_from_main_thread_smoketest.py` imports split
the same way.
`tractor/spawn/_subint_forkserver.py` drops the backward- compat
re-exports of the fork primitives — the only consumers (test file
+ smoketest) now import from `_main_thread_forkserver` directly.
