Replace the B.1 scaffold stub w/ a working spawn
flow driving PEP 734 sub-interpreters on dedicated
OS threads.
Deats,
- use private `_interpreters` C mod (not the public
`concurrent.interpreters` API) to get `'legacy'`
subint config — avoids PEP 684 C-ext compat
issues w/ `msgspec` and other deps missing the
`Py_mod_multiple_interpreters` slot
- bootstrap subint via code-string calling new
`_actor_child_main()` from `_child.py` (shared
entry for both CLI and subint backends)
- drive subint lifetime on an OS thread using
`trio.to_thread.run_sync(_interpreters.exec, ..)`
- full supervision lifecycle mirrors `trio_proc`:
`ipc_server.wait_for_peer()` → send `SpawnSpec`
→ yield `Portal` via `task_status.started()`
- graceful shutdown awaits the subint's inner
`trio.run()` completing; cancel path sends
`portal.cancel_actor()` then waits for thread
join before `_interpreters.destroy()`
Also,
- extract `_actor_child_main()` from `_child.py`
`__main__` block as callable entry shape bc the
subint needs it for code-string bootstrap
- add `"subint"` to the `_runtime.py` spawn-method
check so child accepts `SpawnSpec` over IPC
