## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
In the later development of Airflow 3.0, backward compatibility was not
added for some cases. Thus, the following rules are moved back to AIR302
* airflow.hooks.subprocess.SubprocessResult →
airflow.providers.standard.hooks.subprocess.SubprocessResult
* airflow.hooks.subprocess.working_directory →
airflow.providers.standard.hooks.subprocess.working_directory
* airflow.operators.datetime.target_times_as_dates →
airflow.providers.standard.operators.datetime.target_times_as_dates
* airflow.operators.trigger_dagrun.TriggerDagRunLink →
airflow.providers.standard.operators.trigger_dagrun.TriggerDagRunLink
* airflow.sensors.external_task.ExternalTaskSensorLink →
airflow.providers.standard.sensors.external_task.ExternalDagLink (**This
one contains a minor change**)
* airflow.sensors.time_delta.WaitSensor →
airflow.providers.standard.sensors.time_delta.WaitSensor
## Test Plan
<!-- How was it tested? -->
This primarily comes up with annotated `self` parameters in
constructors:
```py
class C[T]:
def __init__(self: C[int]): ...
```
Here, we want infer a specialization of `{T = int}` for a call that hits
this overload.
Normally when inferring a specialization of a function call, typevars
appear in the parameter annotations, and not in the argument types. In
this case, this is reversed: we need to verify that the `self` argument
(`C[T]`, as we have not yet completed specialization inference) is
assignable to the parameter type `C[int]`.
To do this, we simply look for a typevar/type in both directions when
performing inference, and apply the inferred specialization to argument
types as well as parameter types before verifying assignability.
As a wrinkle, this exposed that we were not checking
subtyping/assignability for function literals correctly. Our function
literal representation includes an optional specialization that should
be applied to the signature. Before, function literals were considered
subtypes of (assignable to) each other only if they were identical Salsa
objects. Two function literals with different specializations should
still be considered subtypes of (assignable to) each other if those
specializations result in the same function signature (typically because
the function doesn't use the typevars in the specialization).

My editor runs `rustfmt` on save to format Rust code, not `cargo fmt`.
With our recent bump to the Rust 2024 edition, the formatting that
`rustfmt`/`cargo fmt` applies changed. Unfortunately, `rustfmt` and
`cargo fmt` have different behaviors for determining which edition to
use when formatting: `cargo fmt` looks for the Rust edition in
`Cargo.toml`, whereas `rustfmt` looks for it in `rustfmt.toml`. As a
result, whenever I save, I have to remember to manually run `cargo fmt`
before committing/pushing.
There is an open issue asking for `rustfmt` to also look at `Cargo.toml`
when it's present (https://github.com/rust-lang/rust.vim/issues/368),
but it seems like they "closed" that issue just by bumping the default
edition (six years ago, from 2015 to 2018).
In the meantime, this PR adds a `rustfmt.toml` file with our current
Rust edition so that both invocation have the same behavior. I don't
love that this duplicates information in `Cargo.toml`, but I've added a
reminder comment there to hopefully ensure that we bump the edition in
both places three years from now.
## Summary
Support direct uses of `typing.TypeAliasType`, as in:
```py
from typing import TypeAliasType
IntOrStr = TypeAliasType("IntOrStr", int | str)
def f(x: IntOrStr) -> None:
reveal_type(x) # revealed: int | str
```

## Ecosystem
The new false positive here:
```diff
+ error[invalid-type-form] altair/utils/core.py:49:53: The first argument to `Callable` must be either a list of types, ParamSpec, Concatenate, or `...`
```
comes from the fact that we infer the second argument as a type
expression now. We silence false positives for PEP695 `ParamSpec`s, but
not for `P = ParamSpec("P")` inside `Callable[P, ...]`.
## Test Plan
New Markdown tests
## Summary
just a minor nit followup to
https://github.com/astral-sh/ruff/pull/18010 -- put all the
non-`Visitor` methods of `SemanticIndexBuilder` in the same impl block
rather than having multiple impl blocks
## Test Plan
`cargo build`
Summary

I noticed these `cfg` directives while working on diagnostics. I think
it makes more sense to apply an `insta` filter in the test instead. I
copied this filter from a CLI test for the same rule.

Existing tests, especially Windows CI on this PR
## Summary
With this PR we now detect that x is always defined in `use`:
```py
if flag and (x := number):
use(x)
```
When outside if, it's still detected as possibly not defined
```py
flag and (x := number)
# error: [possibly-unresolved-reference]
use(x)
```
In order to achieve that, I had to find a way to get access to the
flow-snapshots of the boolean expression when analyzing the flow of the
if statement. I did it by special casing the visitor of boolean
expression to return flow control information, exporting two snapshots -
`maybe_short_circuit` and `no_short_circuit`. When indexing
boolean expression itself we must assume all possible flows, but when
it's inside if statement, we can be smarter than that.
## Test Plan
Fixed existing and added new mdtests.
I went through some of mypy primer results and they look fine
