Wire the backend through every registration site (contract §2)
so `--tpt-proto tipc` is a first-class suite mode,
- `_state.TransportProtocolKey` gains the key
- `_addr._address_types` + `._default_lo_addrs`
- `_addr.wrap_address()` gets a `case ('tipc', *_)`; being a
4-elem seq it can't collide w/ `tcp`s or `uds`s 2-tuple
cases, so NO ordering hazard (and a bare seq-pattern matches
the `list` form `msgpack` decodes to).
- `_types`: the `Address` union, `_msg_transports`,
`_key_to_transport`, `_addr_to_transport` and the
`transport_from_stream()` family match. That last one keys
off `._tipc.AF_TIPC` (which carries the uapi fallback) NOT
`socket.AF_TIPC` which is linux-only.
Test-harness side,
- `get_rando_addr()` gains a `tipc` branch; `.get_random()`
already salts w/ `uuid4`+pid so both within- and cross-proc
isolation come for free.
- the `tpt_protos` fixture calls an addr-type's optional
`.is_available()` and `pytest.fail()`s w/ its reason. Keeps
a module-less box from turning `--tpt-proto tipc` into a few
hundred confusing connect-timeouts. Generic on purpose —
plans 02/03 need the same hook.
- the discovery `daemon` fixture's readiness probe learns to
dial a TIPC service name (it previously assumed tcp-or-uds
and blew up on the 4-tuple).

All `daemon` fixture consumers are discovery-
protocol tests now living under `tests/discovery/`.
Move the fixture, its `_wait_for_daemon_ready`
helper, and `test_multi_program.py` into that subdir
so scope matches usage.
Also,
- add `pytestmark` for `track_orphaned_uds_per_test`
+ `detect_runaway_subactors_per_test` to `test_multi_program` as
regression net.
- drop now-unused `_PROC_SPAWN_WAIT` + `socket` import from root
conftest.
