Introduce the first layer-A address type from the `wg` bindspace
plan without treating a transparent tunnel as a `MsgTransport`.
Deats,
- add frozen `WGTunnelSpec` and `TunnelledAddress` structs which
delegate proto identity, bindspace, validity and wire
serialization to their overlay
- add `strip_tunnels()` and `tunnels_of()` for nested wrappers
- recognize wrappers in `is_wrapped_addr()` while keeping them out
of `_address_types`
- cover delegation, namespace fallback and nested peeling semantics
Also,
- widen `Address.namespace` ids for named netns
- export the new discovery API
- clarify that tractor's layer-C bindspace lifecycle may provision
the kernel-owned bearer without making it a `MsgTransport`

The five transport/address lookup maps each hand-guarded `uds`
with its own `if HAS_UDS:` block (3 in `ipc/_types`, 2 in
`discovery/_addr`) — easy to let drift so a backend half-registers
(known by address but not by key, listed but unroutable, &c).
- build one `_msg_transports` / `_address_protos` list per module
(TCP always, UDS only when `HAS_UDS`), then DERIVE every map
from it via each backend's ClassVars (`codec_key`,
`address_type`, `proto_key`). Adding a backend now touches one
list, and the maps can't disagree.

The prior round gated UDS in four modules but `import tractor`
still crashed on Windows: `tractor.ipc._uds` does `from socket
import AF_UNIX` at module top, and several modules in the import
graph (`discovery._api`, `spawn._reap`, `discovery._multiaddr`,
`_testing.addr`) import `_uds` unconditionally. Instead of
guarding every importer, fix the root and collapse the per-module
probes to one capability flag.
- in `ipc/_uds.py`, guard the lone `AF_UNIX` import so the module
stays importable everywhere; expose `HAS_UDS = trio.has_unix`
as the single source of truth (the same predicate that gates
`trio.open_unix_socket()`).
- `ipc/_types.py`, `discovery/_addr.py` and `ipc/_server.py` now
import `UDSAddress`/`MsgpackUDSStream`/`HAS_UDS` directly and
gate the transport + address registries on `HAS_UDS`; drop the
duplicated `getattr(socket,'AF_UNIX')` / `platform.system()`
probes, the dead `HAS_AF_UNIX` conjunct, and the import-time
`log.warning()` spam.
- `devx/_stackscope.py` `enable_stack_on_sig()` early-returns
when `sig is None`, so a missing `SIGUSR1` (Windows) degrades
to a no-op instead of a `TypeError` from `getsignal()` /
`signal()`.
- add a `windows-latest` CI leg (UDS excluded; informational via
`continue-on-error` while support matures) plus an `import
tractor` smoke step as the hard signal for the import fix.
Because `_uds` is importable everywhere `UDSAddress` stays a real
class, so `isinstance()` checks and `wrap_address()` no longer
`AttributeError` on no-UDS hosts; actual socket use stays gated
on `has_unix`.

Windows (and any CPython that doesn't expose `socket.AF_UNIX`)
can't import the UDS transport backend nor `signal.SIGUSR1`, so
the unconditional imports break `import tractor` outright on
those hosts. Guard the platform-specific bits behind capability
probes and fall back to a TCP-only runtime when the UDS backend
is unavailable.
- across `discovery/_addr.py`, `ipc/_server.py` and
`ipc/_types.py`, gate on `getattr(socket, 'AF_UNIX', None)` +
`platform.system()` and import `UDSAddress` /
`MsgpackUDSStream` only when supported, leaving the names as
`None` otherwise.
- register the `'uds'` key in `_address_types`, its
default-loopback addr, and the transport lookup maps only when
the backend actually loads, so TCP keeps working standalone.
- in `devx/_stackscope.py`, import `SIGUSR1` conditionally and
set it to `None` on Windows.
Rebased onto the post-reorg tree where `_addr.py` now lives
under `tractor/discovery/`; adapt the relocated imports to the
package's `..ipc._uds` / `..ipc._tcp` paths (the original
single-dot paths would silently disable UDS on POSIX) and drop a
duplicated `TYPE_CHECKING` block and dead `import logging` left
by the move.

Provide import-free runtime aliases for annotation-only actor and
multiaddr types so `typing.get_type_hints()` remains usable without
eagerly loading optional dependencies.
Correct `_address_types` to its actual `dict` shape and cover the
affected discovery and transport APIs.

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.

Inverse of `mk_maddr()`: parse a multiaddr string like
`/ip4/127.0.0.1/tcp/1234` back into a tractor `Address`.
Deats,
- add `_maddr_to_tpt_proto` reverse mapping dict
- add `parse_maddr()` fn dispatching on protocol
combo: `[ip4|ip6, tcp]` -> `TCPAddress`,
`[unix]` -> `UDSAddress`
- strip leading `/` the multiaddr lib prepends to
unix protocol values for correct round-trip
- add `str` match case in `wrap_address()` for
`/`-prefixed multiaddr strings, broaden type hint
to `UnwrappedAddress|str`

Restructure the flat `tractor/` top-level private mods
into (more nested) subpackages:
- `runtime/`: `_runtime`, `_portal`, `_rpc`, `_state`,
`_supervise`
- `spawn/`: `_spawn`, `_entry`, `_forkserver_override`,
`_mp_fixup_main`
- `discovery/`: `_addr`, `_discovery`, `_multiaddr`
Each subpkg `__init__.py` is kept lazy (no eager
imports) to avoid circular import issues.
Also,
- update all intra-pkg imports across ~35 mods to use
the new subpkg paths (e.g. `from .runtime._state`
instead of `from ._state`)
