Gud Boi 0a2059d00f Use `tractor.ipc._shm` types directly across codebase ... Port all 16 internal import sites from re-exporting via `piker.data._sharedmem` shim to importing core shm types directly from `tractor.ipc._shm`. Deats, - `ShmArray` now imported from tractor in 10 files. - `_Token` renamed to `NDToken` everywhere (5 files). - `attach_shm_array` → `attach_shm_ndarray` at all call sites. - `data/__init__.py` sources `ShmArray`, `get_shm_token` from tractor; keeps `open/attach_shm_array` as public API aliases. - Trim shim to only piker-specific wrappers: `_make_token()`, `maybe_open_shm_array()`, `try_read()`. - Drop `Optional` usage in shim, use `|None`.
