changelog: allow [`manual_unwrap_or_default`] in const function
This is a small fix, I was originally decided to fix it along with `#12568` but there are some problems needs to be addressed (which is why my branch is called `issue12569` 😆 ), so I decide to open a separated PR to fix them one at a time.
RFC: Document Clippy's teams and team duties
First the big announcement:
**We want to add a new subteam for regular contributors to give them triage rights.**
---
This PR adds a new section to the book which describes the Clippy and Clippy-Contributor teams, with their duties and membership requirements. This is just an initial draft, that outlines what, I think, their responsibilities should be.
I hope everyone in the team is okay with me posting this directly to GitHub. I think a PR makes collaboration a bit easier.

---
Once we've decided on this document, I'll create a PR to add the new team on GitHub. As part of this, we'll also reach out to some active contributors, to ask if they would like to join the new team.

r? `@flip1995`
Remove `unwrap` from `match_trait_method`
Unused_IO_amount relies on `match_trait_method` in order to match trait methods that exist in Tokio traits as the corresponding symbols don't exist.
With this commit we remove the unwrap that caused #12366.
Note: author (`@m-rph)` and `@GuillaumeGomez` couldn't replicate #12366.

Change applicability of `assigning_clones` to `Unspecified`
Before we deal with https://github.com/rust-lang/rust-clippy/pull/12473 and the borrow checker errors, I think that it would be better to downgrade this lint, since it can break code.

[`let_and_return`]: avoid linting when code between last stmt and return expr is cfg'd out
Fixes#9150
This moves `span_contains_cfg` to utils and starts using it in `let_and_return` as well.

fix: `suspicious_else_formatting` false positive when else is included …
This PR addresses an issue where invalid suggestions are generated for `if-else` formatting if comments contain the keyword `else`.
The root of the problem is identified [here](95c62ffae9/clippy_lints/src/formatting.rs (L217)). Specifically, when a comment contains the word `else`, the lint mistakenly interprets it as part of an `if-else` clause. This misinterpretation leads to an incorrect splitting of the snippet, resulting in erroneous suggestions.

Remove unnecessary dot in the 'unconditional recursion' lint description
I don't think such changes should be reflected in the changelog.

`useless_asref`: do not lint `.as_ref().map(Arc::clone)`
This applies to `Arc`, `Rc`, and their weak variants. Using `.clone()` would be less idiomatic.
This follows the discussion in <https://github.com/rust-lang/rust-clippy/issues/12528#issuecomment-2014444305>.

move [`mixed_attributes_style`] to late pass and stop it from linting on different kind of attributes
Do not warn on .map(_::clone) for Arc, Rc, and their weak variants
Those constructions are idiomatic, and using `Arc::clone(x)` and `Rc::clone(x)` is often the recommended way of cloning a `Arc` or a `Rc`.

Fix infinite loop in `cast_sign_loss` when peeling unwrap method calls
Fixes#12506
The lint wants to peel method calls but didn't actually reassign the expression, leading to an infinite loop.

Mention `size_hint()` effect in `flat_map_option` lint documentation.
The previous documentation for `flat_map_option` mentioned only readability benefits, but there is also at least one performance benefit: the `size_hint()` upper bound is preserved, whereas `flat_map().size_hint()` is always `(0, None)`.
Program demonstrating this difference:
```rust
fn main() {
let evens = |i| if i % 2 == 0 { Some(i) } else { None };
dbg!(
[1, 2, 3].iter().flat_map(evens).size_hint(),
[1, 2, 3].iter().filter_map(evens).size_hint(),
);
}
```
changelog: [`flat_map_option`]: Mention the benefit to `size_hint()`.
