## Summary
Resolves https://github.com/astral-sh/ty/issues/1464
We sort the completions before we add the unimported ones, meaning that
imported completions show up before unimported ones.
This is also spoken about in
https://github.com/astral-sh/ty/issues/1274, and this is probably a
duplicate of that.
@AlexWaygood mentions this
[here](https://github.com/astral-sh/ty/issues/1274#issuecomment-3345942698)
too.
## Test Plan
Add a test showing even if an unimported completion "should"
(alphabetically before) come first, we favor the imported one.
Summary
--
This code has been unused since #14233 but not detected by clippy I
guess. This should help to remove the temptation to use the set
comparison again like I suggested in #21144. And we shouldn't do the set
comparison because of #13802, which #14233 fixed.

Fixes https://github.com/astral-sh/ty/issues/1368
## Summary
Add support for patterns like this, where a type alias to a literal type
(or union of literal types) is used to subscript `typing.Literal`:
```py
type MyAlias = Literal[1]
def _(x: Literal[MyAlias]): ...
```
This shows up in the ecosystem report for PEP 613 type alias support.
One interesting case is an alias to `bool` or an enum type. `bool` is an
equivalent type to `Literal[True, False]`, which is a union of literal
types. Similarly an enum type `E` is also equivalent to a union of its
member literal types. Since (for explicit type aliases) we infer the RHS
directly as a type expression, this makes it difficult for us to
distinguish between `bool` and `Literal[True, False]`, so we allow
either one to (or an alias to either one) to appear inside `Literal`,
where other type checkers allow only the latter.
I think for implicit type aliases it may be simpler to support only
types derived from actually subscripting `typing.Literal`, though, so I
didn't make a TODO-comment commitment here.
## Test Plan
Added mdtests, including TODO-filled tests for PEP 613 and implicit type
aliases.
### Conformance suite
All changes here are positive -- we now emit errors on lines that should
be errors. This is a side effect of the new implementation, not the
primary purpose of this PR, but it's still a positive change.
### Ecosystem
Eliminates one ecosystem false positive, where a PEP 695 type alias for
a union of literal types is used to subscript `typing.Literal`.
## Summary
There have been some larger-scale updates to the conformance suite since
we introduced our CI job, so it seems sensible to bump the version of
the conformance suite to the latest state.
## Test plan
This is a bit awkward to test. Here is the diff of running ty on the
conformance suite before and after this bump. I filtered out line/column
information (`sed -re 's/\.py:[0-9]+:[0-9]+:/.py/'`) to avoid spurious
changes from content that has simply been moved around.

## Summary
Adds type inference for list/dict/set comprehensions, including
bidirectional inference:
```py
reveal_type({k: v for k, v in [("a", 1), ("b", 2)]}) # dict[Unknown | str, Unknown | int]
squares: list[int | None] = [x for x in range(10)]
reveal_type(squares) # list[int | None]
```
## Ecosystem impact
I did spot check the changes and most of them seem like known
limitations or true positives. Without proper bidirectional inference,
we saw a lot of false positives.
## Test Plan
New Markdown tests
