First half of the `brokerd` split: a new per-provider
data-feed-only daemon-actor `datad.<broker>` to (soon) host
all `validate._eps['datad']` eps (live quotes, history
loading, symbology search) leaving `brokerd` for live order
ctl only. Purely additive; nothing routes through it yet.
Deats,
- new `piker.data._daemon` mod mirroring the
`.brokers._daemon` conventions (and the `samplerd`
sub-daemon precedent):
- `_setup_persistent_datad()` lifetime fixture owning the
actor-global `_FeedsBus` alloc.
- `datad_init()` building `enable_modules` from the
backend's `_datad_mods` (falling back to
`__enable_modules__` for not-yet-split backends) and
copying `_spawn_kwargs` (critical for `ib`'s
`infect_asyncio`).
- `spawn_datad()`/`maybe_spawn_datad()` wrapping
`Services` + `maybe_spawn_daemon()`.
- add `piker.data._daemon` to `_root_modules` so `pikerd`
can run `spawn_datad()` requests.
- re-export the spawn eps from `piker.service`.
- add `test_datad_spawn` verifying actor boot + service
registration via `ensure_service('datad.kraken')`.
Note the `Services`-based impl style deliberately mirrors
`spawn_brokerd()` so the eventual `tractor.hilevel`
`ServiceMngr` port (see the `service_mng_to_tractor`
branch's d8c21d44 prep work) lands symmetrically on both.

Prep for the `brokerd` -> (`datad` + `brokerd`) actor split
by having each (split-style) backend declare which of its
submods host which daemon-kind's eps, exactly per the
`piker.data.validate._eps` groupings; `ib` already had
`_brokerd_mods`/`_datad_mods` so extend the convention to
`kraken`, `binance` and `deribit` (and add `'api'` to ib's
datad set since both kinds need the `Client` layer).
`__enable_modules__` stays as the (deduped) union so this
is a ZERO behavior change; flat backends (`kucoin` etc.)
just don't declare the split yet.
Also,
- add `validate.get_eps()` returning a backend's defined
eps per daemon-kind for spawn-time introspection.
- import `NoBsWs`/`open_autorecon_ws` from
`piker.data._web_bs` directly in `.kraken.broker` (they
were only re-exported via `.kraken.feed`) so the trading
mod doesn't depend on the feed mod for ws primitives.

Continue the `repair_tests`-branch mission (already merged
in this stack's ancestry, see f4c4f1e2 which ported
`conftest.py`) by fixing the remaining drift breakage vs.
`tractor` git `main`; without these NOTHING boots since the
`tractor.Address` port in 604e5fcf.
Deats,
- normalize reg addrs via `wrap_address()` in
`open_pikerd()` before `.unwrap()`-ing; entries may be
raw `tuple`s when passed in from (test) client code.
- port `check_for_service()` to `query_actor(regaddr=)`
(was `arbiter_sockaddr=`) incl. its 2-tuple yield and
the now-required `open_registry(addrs=)` arg.
- `wait_for_actor(registry_addr=)` + `.chan.raddr.unwrap()`
raw-tuple compares in `test_runtime_boot` and
`ensure_service()`.
- update `run_test_w_cancel_method()` for modern `tractor`
cancel semantics: self-requested sub-service cancels are
absorbed (no `ContextCancelled` raised to the opener) and
single-exc groups collapse to a bare KBI.
- `RemoteActorError.boxed_type` (was `.type`) and
`Position.cumsize` (was `.size`) renames in tests.
- bump the paper-EMS startup budget 9 -> 19s; it includes
a live (kraken) symbology fetch so needs net headroom.
- woops, add the missing comma in `.deribit.api`'s
`tractor.trionics` import tuple..

The old (commented-out) `get_app_dir()` override gated on
`'pytest' in sys.modules` which can NEVER work in spawned
subactors (fresh procs, no pytest import); as a result test
`paperboi`/daemon actors were writing into the user's REAL
`~/.config/piker/accounting/` files.. friggin yikes.
Deats,
- add `config._maybe_use_test_dir()` which lazily (at
conf-path access time, NOT import time) reads the
`piker_test_dir` entry from
`tractor.runtime._state._runtime_vars['piker_vars']` as
pre-loaded by `open_piker_runtime()` from the
`tests.conftest._open_test_pikerd()` overrides.
- hook it in `get_conf_dir()` and route `get_conf_path()`
+ `load()`'s mkdir through `get_conf_dir()`.
- route `.accounting._ledger` / `._pos` dir derivation
through `config.get_conf_dir()` (was reading the
`_config_dir` global directly, bypassing the override);
also `mkdir(parents=True, exist_ok=True)` for nested
tmp-dir creation.
