Gud Boi 4b2a0886c3 Mark `subint`-hanging tests with `skipon_spawn_backend`
Adopt the `@pytest.mark.skipon_spawn_backend('subint',
reason=...)` marker (a617b521) across the suites
reproducing the `subint` GIL-contention / starvation
hang classes doc'd in `ai/conc-anal/subint_*_issue.md`.

Deats,
- Module-level `pytestmark` on full-file-hanging suites:
  - `tests/test_cancellation.py`
  - `tests/test_inter_peer_cancellation.py`
  - `tests/test_pubsub.py`
  - `tests/test_shm.py`
- Per-test decorator where only one test in the file
  hangs:
  - `tests/discovery/test_registrar.py
    ::test_stale_entry_is_deleted` — replaces the
    inline `if start_method == 'subint': pytest.skip`
    branch with a declarative skip.
  - `tests/test_subint_cancellation.py
    ::test_subint_non_checkpointing_child`.
- A few per-test decorators are left commented-in-
  place as breadcrumbs for later finer-grained unskips.

Also, some nearby tidying in the affected files:
- Annotate loose fixture / test params
  (`pytest.FixtureRequest`, `str`, `tuple`, `bool`) in
  `tests/conftest.py`, `tests/devx/conftest.py`, and
  `tests/test_cancellation.py`.
- Normalize `"""..."""` → `'''...'''` docstrings per
  repo convention on a few touched tests.
- Add `timeout=6` / `timeout=10` to
  `@tractor_test(...)` on `test_cancel_infinite_streamer`
  and `test_some_cancels_all`.
- Drop redundant `spawn_backend` param from
  `test_cancel_via_SIGINT`; use `start_method` in the
  `'mp' in ...` check instead.
