new lint: `zombie_processes`
Closes#10754
Lint description should explain this PR, so I think there's nothing else to say here ^^
changelog: new lint: [`zombie_processes`]
Add new lint: `used_underscore_items`
Closes#13260

changelog: new [`used_underscore_items`] lint against using items with a single leading underscore
Fix manual_range_patterns case with one element at OR
Close#11825
As mentioned #11825 `OR` can be used for stylistic purposes with one element, we can filter this case from triggering lint
changelog: [`manual_range_patterns`]: not trigger when `OR` has only one element
check std::panic::panic_any in panic lint
close#13292
This PR detects `std::panic::panic_any` in panic lint.

Rewrite `empty_line_after_doc_comments` and `empty_line_after_outer_attr`, move them from `nursery` to `suspicious`
changelog: [`empty_line_after_doc_comments`], [`empty_line_after_outer_attr`]: rewrite and move them from `nursery` to `suspicious`
They now lint when there's a comment between the last attr/doc comment and the empty line, to cover the case:
```rust
/// Docs for `old_code
// fn old_code() {}
fn new_code() {}
```
When these lints or `suspicious_doc_comments` trigger we no longer trigger any other doc lint as a broad fix for #12917, reverts some of #13002 as the empty line lints cover it
I ended up not doing https://github.com/rust-lang/rust-clippy/issues/12917#issuecomment-2161828859 as I don't think it's needed
Ignore underscore-prefixed args for needless_pass_by_value lint
When a user explicitly tags a param as unused (yet?), there is no need to raise another lint on it.
fixes#7295
Note that I had to rename all `_*` params in the tests, but kept the variable name length to avoid extra changes in the expected output.
changelog: [`needless_pass_by_value`]: do not warn if the argument name starts with an `_`
Diverging subexpression lint should not fire on todo!()
As per #10243 it is not that helpful to point out that a subexpression diverges, so do not fire on todo
changelog: [`diverging_sub_expression`]: do not trigger on todo
Fix confusing message in double_must_use lint
Close#13003
As mentioned at #13003 it isn't quite clear what it means "an empty `#[must_use]` attribute" so clarify it
changelog: [none]

changelog: fix false positive in explicit_iter_loop when msrv < 1.80
Remove `find_format_arg_expr` AST fallback
If the function fails where it shouldn't we can fix that directly, but the fallback path is untested as I'm not aware of a case where it would fail

Disable assigning_clones for tests
Close: #12752
As mentioned at #12752 when a test struct is initialized with some default string, this inverts the order of assignee/assignment and makes a bit harder to read/write code
changelog: [`assigning_clones.rs`]: disable assigning_clones for tests
