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.

(cherry picked from commit 4b2a0886c3)
(factored: dropped spawn-backend-only path: tests/test_subint_cancellation.py)
Add a hard process-level wall-clock bound on a test
known to wedge un-Ctrl-C-ably under an in-dev spawn
backend, so an unattended suite run can't hang
indefinitely.
Deats,
- New `testing` dep: `pytest-timeout>=2.3`.
- `test_stale_entry_is_deleted`:
`@pytest.mark.timeout(3, method='thread')`. The
`method='thread'` choice is deliberate —
`method='signal'` routes via `SIGALRM` which can be
starved by the same GIL-hostage path that drops
`SIGINT`, so it'd never actually fire in the
starvation case.
At timeout, `pytest-timeout` hard-kills the pytest
process itself — that's the intended behavior here;
the alternative is the suite never returning.

(cherry picked from commit 189f4e3f72e9f1eda5d24bcbab5743f7e35bd913)
(factored: kept pyproject + tests/discovery/test_registrar.py parts of
"Wall-cap `subint` audit tests via `pytest-timeout`"; dropped
tests/test_subint_cancellation.py)
Wrap the test's `trio.run(main)` in
`dump_on_hang(seconds=20)` so any future hang
regression captures a stack dump for triage instead
of wedging CI silently; under the default backends
it's a no-op safety net.
Includes a "KNOWN ISSUE" comment block documenting
the (future) `subint` backend hang classes observed
against this test during Phase B bringup (#379).

Cover `parse_maddr()` with unit tests for tcp/ipv4,
tcp/ipv6, uds, and unsupported-protocol error paths,
plus full `addr -> mk_maddr -> str -> parse_maddr`
roundtrip verification.
Adds,
- a `_maddr_to_tpt_proto` inverse-mapping assertion.
- an `wrap_address()` maddr-string acceptance test.
- a `test_reg_then_unreg_maddr` end-to-end suite which audits passing
the registry addr as multiaddr str through the entire runtime.

All tests are registrar-actor integration scenarios
sharing intertwined helpers + `enable_modules=[__name__]`
task fns, so keep as one mod but rename to reflect
content. Now lives alongside `test_multiaddr.py` in
the new `tests/discovery/` subpkg.
Also,
- update 5 refs in `/run-tests` SKILL.md to match
the new path
- add `discovery/` subdir to the test directory
layout tree
