[ty] List available members for a given type (#18251)
This PR adds initial support for listing all attributes of
an object. It is exposed through a new `all_members`
routine in `ty_extensions`, which is in turn used to test
the functionality.

The purpose of listing all members is for code
completion. That is, given a `object.<CURSOR>`, we
would like to list all available attributes on
`object`.

[ty] Implement Python's floor division semantics for Literal ints (#18249)
Division works differently in Python than in Rust. If the result is
negative and there is a remainder, the division rounds down (instead of
towards zero). The remainder needs to be adjusted to compensate so that
`(lhs // rhs) * rhs + (lhs % rhs) == lhs`.

Fixes astral-sh/ty#481.

[ty Playground] Release / publish (push) Waiting to run
This updates our function specialization inference to infer type
mappings from parameters that are generic aliases, e.g.:

```py
def f[T](x: list[T]) -> T: ...

reveal_type(f(["a", "b"]))  # revealed: str
```

Though note that we're still inferring the type of list literals as
`list[Unknown]`, so for now we actually need something like the
following in our tests:

```py
def _(x: list[str]):
    reveal_type(f(x))  # revealed: str
```
