Part of #15584
This PR adds a fix safety section to `PIE794`
I could not track down when this rule was initially implemented/made
unsafe due how old it could be + multiple large refactors to `ruff`.
There is no comment/reasoning in the code given for the unsafety.
Here is a code example demonstrating why it should be unsafe, since
removing any of the assignments would change program behavior
[playground](https://play.ruff.rs/01004644-4259-4449-a581-5007cd59846a)
```py
class A:
x = 1
x = 2
print(x)
class B:
x = print(3)
x = print(4)
class C:
x = [1,2,3]
y = x
x = y[1]
```

Essentially this PR ensures that when we do fixes like this:
```diff
- t"{set(f(x) for x in foo)}"
+ t"{ {f(x) for x in foo} }"
```
we are correctly adding whitespace around the braces.
This logic is already in place for f-strings and just needed to be
generalized to interpolated strings.
Summary
--
This PR unifies the remaining differences between `OldDiagnostic` and
`Message` (`OldDiagnostic` was only missing an optional `noqa_offset`
field) and
replaces `Message` with `OldDiagnostic`.
The biggest functional difference is that the combined `OldDiagnostic`
kind no
longer implements `AsRule` for an infallible conversion to `Rule`. This
was
pretty easy to work around with `is_some_and` and `is_none_or` in the
few places
it was needed. In `LintContext::report_diagnostic_if_enabled` we can
just use
the new `Violation::rule` method, which takes care of most cases.
Most of the interesting changes are in [this
range](8156992540)
before I started renaming.

I think it's time to start shifting some of these fields to the new
`Diagnostic`
kind. I believe we want `Fix` for sure, but I'm less sure about the
others. We
may want to keep a thin wrapper type here anyway to implement a `rule`
method,
so we could leave some of these fields on that too.
## Summary
This PR avoids the `Vec::retain` call in `check_tokens` by checking if
rules are enabled as their diagnostics are constructed.
2a425e43fd/crates/ruff_linter/src/checkers/tokens.rs (L174-L176)
Since `LintContext::report_diagnostic_if_enabled` required a
`LinterSettings`, I added a `settings` field to the context itself
instead of trying to pass it everywhere. This also turned
`LogicalLinesContext` into a trivial wrapper around `LintContext`, so I
just removed it in favor of using `LintContext` directly too.
The diff is a bit smaller with whitespace hidden since many blocks got
moved into something like this:
```rust
if let Some(mut diagnostic) = context.report_diagnostic.enabled(...) {
// old code
}
```
## Test Plan
Existing tests
When I try to grep CPython with `__super__` I get 0 results:
```
(.venv) ~/Desktop/cpython main ✔
» ag __super__ .
```
That's how we can understand that the naming is not the best.
This involved slightly more code changes than usual for a stabilization
- so maybe worth double-checking the logic!
I did verify by hand that the new stable behavior on the test fixture
matches the old preview behavior, even after the internal refactor.
Summary

Deprecates PD901 as part of #7710. I don't feel particularly strongly
about this one, though I have certainly used `df` as a dataframe name in
the past, just going through the open issues in the 0.12 milestone.

## Summary
- Stabilizes RUF058 (starmap-zip) rule by changing it from Preview to
Stable
- Migrates test cases from preview_rules to main rules function
- Updates snapshots accordingly and removes old preview snapshots
## Test plan
- ✅ Migrated tests from preview to main test function
- ✅ `make check` passes
- ✅ `make test` passes
- ✅ `make citest` passes (no leftover snapshots)
## Rule Documentation
- [Test
file](https://github.com/astral-sh/ruff/blob/main/crates/ruff_linter/src/rules/ruff/mod.rs#L103-L104)
- [Rule documentation](https://docs.astral.sh/ruff/rules/starmap-zip/)
## Summary
Stabilizes the UP049 rule (private-type-parameter) by moving it from
Preview to Stable.
UP049 detects and fixes the use of private type parameters (those with
leading underscores) in PEP 695 generic classes and functions.
## Test plan
- Verified that UP049 tests pass:
`crates/ruff_linter/src/rules/pyupgrade/mod.rs`
- Ran full test suite with `make test`
- Confirmed that no test migration was needed as UP049 was already in
the main `rules` test function
## Rule documentation
https://docs.astral.sh/ruff/rules/private-type-parameter/
Note that the preview behavior was not documented (shame on us!) so the
documentation was not modified.

This PR stabilizes the FURB162 rule by moving it from preview to stable
status for the 0.12.0 release.
## Summary
- **Rule**: FURB162 (`fromisoformat-replace-z`)
- **Purpose**: Detects unnecessary timezone replacement operations when
calling `datetime.fromisoformat()`
- **Change**: Move from `RuleGroup::Preview` to `RuleGroup::Stable` in
`codes.rs`
## Verification Links
- **Tests**:
[refurb/mod.rs](https://github.com/astral-sh/ruff/blob/main/crates/ruff_linter/src/rules/refurb/mod.rs#L54)
- Confirms FURB162 has only standard tests, no preview-specific test
cases
- **Documentation**:
https://docs.astral.sh/ruff/rules/fromisoformat-replace-z/ - Current
documentation shows preview status that will be automatically updated
