Add prompt-io entries for gh #470 latency work

Log the AI-assisted session per the NLNet generative-AI policy: prompt, profiling findings, per-file diff pointers, measured results and the unimplemented `pdbp`/`platformdirs` deferral follow-ups.

Gud Boi	2049f6082b	Defer `asyncio` import via PEP-562 `.to_asyncio` `asyncio` (~5ms) only matters for infected-aio actors yet gets imported by every cold `import tractor` via module-lvl `.to_asyncio` imports in the debug-REPL + spawn-entry mods. Deats, - `devx.debug._trace`/`._tty_lock`: mv `import asyncio` under `TYPE_CHECKING` + fn-local it at the two `asyncio.current_task()` call-sites; fn-local the `run_trio_task_in_future` imports in the infected-aio-only branches. - `spawn._entry`: fn-local `run_as_asyncio_guest` inside the `infect_asyncio=True` branches of `_mp_main()`/ `_trio_main()`. - `tractor/__init__.py`: add a PEP-562 module `__getattr__` lazy-loading `.to_asyncio` on first attr-access so the public `tractor.to_asyncio.<attr>` API (e.g. `LinkedTaskChannel` annots in `test_child_manages_service_nursery.py` + downstream users) keeps working unchanged.

Gud Boi	efeb6c148c	Lazy-import optional 3rd-party deps (gh #470 ) Move every import-time-only-by-accident dep off the eager `import tractor` path so cold child-actor boots only pay for what they actually use: - `bidict` -> `TYPE_CHECKING` in `discovery._addr` (annotation-only; `_address_types` is a plain `dict` literal). - `multiaddr` -> `TYPE_CHECKING` + fn-local imports in `discovery._multiaddr.mk_maddr()`/`parse_maddr()`; also `TYPE_CHECKING` the `Multiaddr` annots in `ipc._tcp`/`._uds` (adds future-annots to `._multiaddr`). - `colorlog` -> fn-local in `log.get_console_log()`. - `pdbp` + `wrapt` -> fn-local in `devx._frame_stack.hide_runtime_frames()`/`api_frame()`. - `platformdirs` -> fn-local in `runtime._state.get_rt_dir()`. Still eager (documented follow-ups), - `pdbp` via `devx.debug._repl` class-bases (`PdbREPL(pdbp.Pdb)`) + the module-lvl `@pdbp.hideframe` in `._tty_lock`; needs a `._repl` restructure. - `platformdirs` via the `UDSAddress.def_bindspace: ClassVar` class-body eval of `get_rt_dir()`; needs an `Address`-proto rework. - `stackscope` is already fn-local; `setproctitle` is not imported anywhere.

Gud Boi	028259b0bc	Use `sys._getframe()` in `get_logger()` mod lookup `get_caller_mod()` (nested in `get_logger()`) walks the WHOLE call-stack via `inspect.stack()`, which also resolves src-file info for every frame and scans all of `sys.modules` per frame via `inspect.getmodule()`. During nested imports (deep importlib stacks) each module-level `get_logger()` call costs ~5-10ms, making the ~39 such calls dominate `import tractor` wall-time: ~244ms of the ~420ms total (see gh #470). Deats, - resolve the caller frame with `sys._getframe(frames_up)` and map its `f_globals['__name__']` through `sys.modules`: O(1) vs. O(stack x sys.modules). - guard `ValueError` (stack too shallow) -> `None`, matching the existing null-caller handling at all use-sites. - drop the now-unused `inspect` imports; pull `FrameType` from `types` instead. Results: `import tractor` drops 0.42s -> ~0.155s; sequential `.start_actor()` spawn latency ~0.42 -> ~0.18s/actor.
