First test-file of the #477 `.run_in_actor()` removal (blocking
`to_actor.run()` is the successor; the legacy non-blocking one-shot
is dropped, not replaced). All 9 call-sites migrated,
- blocking result/error/streaming-result tests -> `to_actor.run(fn,
an=an, ...)`; the "streaming" ones stream aio<->trio INSIDE the
subactor so the caller only awaits the final result.
- forever-task + cancel tests (`test_tractor_cancels_aio`,
`test_trio_cancels_aio`) -> `start_actor()` +
`Portal.open_context()` + cancel — can't block on a
never-returning task. Adds a small `sleep_forever_aio_ctx`
`@context` shim.
- greens the red `test_tractor_cancels_aio` anti-hang guard from
the prior commit: under the correctly-scoped API the wait is
bounded by the caller's cancel scope, so the hang is structurally
gone — not patched.
Suite: 34 passed, 2 xfailed (trio backend).
