## Summary
Trailing ellipses in objects defined in `typing.TYPE_CHECKING` might be
meaningful (it might be declaring a stub). Thus, we should skip the
`unnecessary-placeholder` (`PIE970`) rule in such contexts.
Closes#10358.
## Test Plan
`cargo nextest run`
## Summary
It turns out that some type checkers rely on the presence of ellipses in
`Protocol` interfaces and abstract methods, in order to differentiate
between default implementations and stubs. This PR modifies the preview
behavior of `PIE790` to avoid flagging "unnecessary" ellipses in such
cases.
Closes https://github.com/astral-sh/ruff/issues/8756.
## Test Plan
`cargo test`
## Summary
This PR extends `unnecessary-pass` (`PIE790`) to flag unnecessary
ellipsis expressions in addition to `pass` statements. A `pass` is
equivalent to a standalone `...`, so it feels correct to me that a
single rule should cover both cases.
When we look to v0.2.0, we should also consider deprecating `PYI013`,
which flags ellipses only for classes.
Closes https://github.com/astral-sh/ruff/issues/8602.
## Summary
This wasn't necessary in the past, since we _only_ applied this rule to
bodies that contained two statements, one of which was a `pass`. Now
that it applies to any `pass` in a block with multiple statements, we
can run into situations in which we remove both passes, and so need to
apply the fixes in isolation.

## Summary
Extend `unnecessary-pass` (`PIE790`) to trigger on all unnecessary
`pass` statements by checking for `pass` statements in any class or
function body with more than one statement.
Closes#7600.
## Test Plan
`cargo test`
