## Summary
This PR improves the fix for `PYI055` to be able to handle nested and
mixed type unions.
It also marks the fix as unsafe when comments are present.

<!-- What's the purpose of the change? What does it do, and why? -->
`pytest-raises-too-broad (PT011)` should be raised when
`expected_exception` is provided as a keyword argument.
```python
def test_foo():
with pytest.raises(ValueError): # raises PT011
raise ValueError("Can't divide 1 by 0")
# This is minor but a valid pytest.raises call
with pytest.raises(expected_exception=ValueError): # doesn't raise PT011 but should
raise ValueError("Can't divide 1 by 0")
```

## Summary
- Emit diagnostics when looking up (possibly) unbound attributes
- More explicit test assertions for unbound symbols
- Review remaining call sites of `Symbol::ignore_possibly_unbound`. Most
of them are something like `builtins_symbol(self.db,
"Ellipsis").ignore_possibly_unbound().unwrap_or(Type::Unknown)` which
look okay to me, unless we want to emit additional diagnostics. There is
one additional case in enum literal handling, which has a TODO comment
anyway.
part of #14022
## Test Plan
New MD tests for (possibly) unbound attributes.
## Summary
This adds a new diagnostic when possibly unbound symbols are imported.
The `TODO` comment had a question mark, do I'm not sure if this is
really something that we want.
This does not touch the un*declared* case, yet.
relates to: #14022
## Test Plan
Updated already existing tests with new diagnostics
## Summary
Apart from one small functional change, this is mostly a refactoring of
the `Symbol` API:
- Rename `as_type` to the more explicit `ignore_possibly_unbound`, no
functional change
- Remove `unwrap_or_unknown` in favor of the more explicit
`.ignore_possibly_unbound().unwrap_or(Type::Unknown)`, no functional
change
- Consistently call it "possibly unbound" (not "may be unbound")
- Rename `replace_unbound_with` to `or_fall_back_to` and properly handle
boundness of the fall back. This is the only functional change (did not
have any impact on existing tests).
relates to: #14022
## Test Plan
New unit tests for `Symbol::or_fall_back_to`

## Summary
The implicit namespace package rule currently fails to detect cases like
the following:
```text
foo/
├── __init__.py
└── bar/
└── baz/
└── __init__.py
```
The problem is that we detect a root at `foo`, and then an independent
root at `baz`. We _would_ detect that `bar` is an implicit namespace
package, but it doesn't contain any files! So we never check it, and
have no place to raise the diagnostic.
This PR adds detection for these kinds of nested packages, and augments
the `INP` rule to flag the `__init__.py` file above with a specialized
message. As a side effect, I've introduced a dedicated `PackageRoot`
struct which we can pass around in lieu of Yet Another `Path`.
For now, I'm only enabling this in preview (and the approach doesn't
affect any other rules). It's a bug fix, but it may end up expanding the
rule.
Closes https://github.com/astral-sh/ruff/issues/13519.
## Summary
It's only safe to enforce the `x in "1234567890"` case if `x` is exactly
one character, since the set on the right has been reordered as compared
to `string.digits`. We can't know if `x` is exactly one character unless
it's a literal. And if it's a literal, well, it's kind of silly code in
the first place?
Closes https://github.com/astral-sh/ruff/issues/13802.
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Fix `await-outside-async` to allow `await` at the top-level scope of a
notebook.
```python
# foo.ipynb
await asyncio.sleep(1) # should be allowed
```
## Test Plan

This PR accounts for further subtleties in `Decimal` parsing:
- Strings which are empty modulo underscores and surrounding whitespace
are skipped
- `Decimal("-0")` is skipped
- `Decimal("{integer literal that is longer than 640 digits}")` are
skipped (see linked issue for explanation)
NB: The snapshot did not need to be updated since the new test cases are
"Ok" instances and added below the diff.
Closes#14204
