Update mypy-dev to 1.12.0a1

[cdce8p]

Proposed change

https://github.com/cdce8p/mypy-dev/releases/tag/1.12.0a1
Compare: python/mypy@39b9b89...6d45f3c

New features:

• Infer unions for ternary expressions python/mypy#17427
  New issues were already fixed in Typing improvements #120297
• Experimental: allow inline/anonymous TypedDicts python/mypy#17457
  Not sure this is useful for us at this point as it isn't defined in a PEP yet. Anyway, it will allow us to experiment with it. Maybe we find a good use case for it.

What's InlineTypedDict?

https://mypy.readthedocs.io/en/latest/typed_dict.html#inline-typeddict-types
Probably the most useful case for us would have been nested TypedDicts like in the registry helpers.

-class _FloorStoreData(TypedDict):
-    aliases: list[str]
-    floor_id: str
-    icon: str | None
-    level: int | None
-    name: str
-
-
 class FloorRegistryStoreData(TypedDict):
-    floors: list[_FloorStoreData]
+    floors: list[
+        {
+            "aliases": list[str],
+            "floor_id": str,
+            "icon": str | None,
+            "level": int | None,
+            "name": str,
+        }
+    ]

I don't think we show enable this, mostly because of the release notes @ pyright

Yeah, it's unfortunate that it got removed from pyright. Tbh the setting would have been more useful for general experimentation than anything else. Mostly because the mypy cache gets invalidated if the global settings change. I removed it. Let's hope the PEP gets of the ground eventually.
