## Summary
It's common practice to name derive macros the same as the trait that they implement (`Debug`, `Display`, `Eq`, `Serialize`, ...).
This PR renames the `ConfigurationOptions` derive macro to `OptionsMetadata` to match the trait name.
## Test Plan
`cargo build`
## Summary
This PR adds a new `lint` section to the configuration that groups all linter-specific settings. The existing top-level configurations continue to work without any warning because the `lint.*` settings are experimental.
The configuration merges the top level and `lint.*` settings where the settings in `lint` have higher precedence (override the top-level settings). The reasoning behind this is that the settings in `lint.` are more specific and more specific settings should override less specific settings.
I decided against showing the new `lint.*` options on our website because it would make the page extremely long (it's technically easy to do, just attribute `lint` with `[option_group`]). We may want to explore adding an `alias` field to the `option` attribute and show the alias on the website along with its regular name.
## Test Plan
* I added new integration tests
* I verified that the generated `options.md` is identical
* Verified the default settings in the playground

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Extends work in #7046 (some relevant discussion there)
Changes:
- All nursery rules are now referred to as preview rules
- Documentation for the nursery is updated to describe preview
- Adds a "PREVIEW" selector for preview rules
- This is primarily to allow `--preview --ignore PREVIEW --extend-select
FOO001,BAR200`
- Using `--preview` enables preview rules that match selectors
Notable decisions:
- Preview rules are not selectable by their rule code without enabling
preview
- Retains the "NURSERY" selector for backwards compatibility
- Nursery rules are selectable by their rule code for backwards
compatiblity
Additional work:
- Selection of preview rules without the "--preview" flag should display
a warning
- Use of deprecated nursery selection behavior should display a warning
- Nursery selection should be removed after some time
## Test Plan
<!-- How was it tested? -->
Manual confirmation (i.e. we don't have an preview rules yet just
nursery rules so I added a preview rule for manual testing)
New unit tests

## Summary
This is the result of running `cargo +nightly clippy --workspace
--all-targets --all-features -- -D warnings` and fixing all violations.
Just wanted to see if there were any interesting new checks on nightly
👀
## Summary
As discussed on ~IRC~ Discord, this will make it easier for e.g. the
docs generation stuff to get all rules for a linter (using
`all_rules()`) instead of just non-nursery ones, and it also makes it
more Explicit Is Better Than Implicit to iterate over linter rules.
Grepping for `Item = Rule` reveals some remaining implicit
`IntoIterator`s that I didn't feel were necessarily in scope for this
(and honestly, iterating over a `RuleSet` makes sense).
Support for `let…else` formatting was just merged to nightly
(rust-lang/rust#113225). Rerun `cargo fmt` with Rust nightly 2023-07-02
to pick this up. Followup to #939.

## Summary
Ensures that `--select PL` and `--select PLC` don't include `PLC1901`.
Previously, `--select PL` _did_, because it's a "linter-level selector"
(`--select PLC` is viewed as selecting the `C` prefix from `PL`), and we
were missing this filtering path.
## Summary
Add copyright notice detection to enforce the presence of copyright
headers in Python files.
Configurable settings include: the relevant regular expression, the
author name, and the minimum file size, similar to
[flake8-copyright](https://github.com/savoirfairelinux/flake8-copyright).

## Summary
This PR moves `Diagnostic`, `DiagnosticKind`, and `Fix` into their own crate, which will enable us to further split up Ruff, since sub-linter crates (which need to implement functions that return `Diagnostic`) can now depend on `ruff_diagnostics` rather than Ruff.
This PR introduces a new `CacheKey` trait for types that can be used as a cache key.
I'm not entirely sure if this is worth the "overhead", but I was surprised to find `HashableHashSet` and got scared when I looked at the time complexity of the `hash` function. These implementations must be extremely slow in hashed collections.
I then searched for usages and quickly realized that only the cache uses these `Hash` implementations, where performance is less sensitive.
This PR introduces a new `CacheKey` trait to communicate the difference between a hash and computing a key for the cache. The new trait can be implemented for types that don't implement `Hash` for performance reasons, and we can define additional constraints on the implementation: For example, we'll want to enforce portability when we add remote caching support. Using a different trait further allows us not to implement it for types without stable identities (e.g. pointers) or use other implementations than the standard hash function.
For example:
$ ruff check --select=EM<Tab>
EM -- flake8-errmsg
EM10 EM1 --
EM101 -- raw-string-in-exception
EM102 -- f-string-in-exception
EM103 -- dot-format-in-exception

in the Autocompletion section in the README.)
Fixes#2808.
(The --help help change in the README is due to a clap bug,
for which I already submitted a fix:
