(Supersedes #9152, authored by @LaBatata101)
## Summary
This PR replaces the current parser generated from LALRPOP to a
hand-written recursive descent parser.
It also updates the grammar for [PEP
646](https://peps.python.org/pep-0646/) so that the parser outputs the
correct AST. For example, in `data[*x]`, the index expression is now a
tuple with a single starred expression instead of just a starred
expression.
Beyond the performance improvements, the parser is also error resilient
and can provide better error messages. The behavior as seen by any
downstream tools isn't changed. That is, the linter and formatter can
still assume that the parser will _stop_ at the first syntax error. This
will be updated in the following months.
For more details about the change here, refer to the PR corresponding to
the individual commits and the release blog post.
## Test Plan
Write _lots_ and _lots_ of tests for both valid and invalid syntax and
verify the output.

## Summary
Fixes#10367.
While the server is still in an unstable state, requiring a `--preview`
flag would be a good way to indicate this to end users.
## Summary
Long ago, we had a single `ruff` crate. We started to break that up, and
at some point, we wanted to separate the CLI from the core library. So
we created `ruff_cli`, which created a `ruff` binary. Later, the `ruff`
crate was renamed to `ruff_linter` and further broken up into additional
crates.
(This is all from memory -- I didn't bother to look through the history
to ensure that this is 100% correct :))
Now that `ruff` no longer exists, this PR renames `ruff_cli` to `ruff`.
The primary benefit is that the binary target and the crate name are now
the same, which helps with downstream tooling like `cargo-dist`, and
also removes some complexity from the crate and `Cargo.toml` itself.
## Test Plan
- Ran `rm -rf target/release`.
- Ran `cargo build --release`.
- Verified that `./target/release/ruff` was created.
## Summary
We stopped releasing this a while ago and no longer advertise it
anywhere. IMO, we should remove it so that we stop paying the cost of
maintaining it. If we want to revive it, we can always do so from Git.
I'd rather not be the only one who can easily generate our changelog
entries so I invested some time to get Rooster a bit further along and
add instructions.
**Summary** Simplify CI by ensuring that the source distribution is
always built with the rust version that has been explicitly tested. See
discussion in #8389Closes#8389

## Summary
Tiny updates on packaging metadata:
- mention code formatting in description
- link to changelog instead of releases, now that a changelog file
exists and updated on each release
- Add changelog entry for 0.1.1
- Bump version to 0.1.1
- Require preview for fix added in #7967
- Allow duplicate headings in changelog (markdownlint setting)
## Summary
We're planning to move the documentation from
[https://beta.ruff.rs/docs](https://beta.ruff.rs/docs) to
[https://docs.astral.sh/ruff](https://docs.astral.sh/ruff), for a few
reasons:
1. We want to remove the `beta` from the domain, as Ruff is no longer
considered beta software.
2. We want to migrate to a structure that could accommodate multiple
future tools living under one domain.
The docs are actually already live at
[https://docs.astral.sh/ruff](https://docs.astral.sh/ruff), but later
today, I'll add a permanent redirect from the previous to the new
domain. **All existing links will continue to work, now and in
perpetuity.**
This PR contains the code changes necessary for the updated
documentation. As part of this effort, I moved the playground and
documentation from my personal Cloudflare account to our team Cloudflare
account (hence the new `--project-name` references). After merging, I'll
also update the secrets on this repo.
