## Summary
Provide instructions to use Ruff together with other servers in the Kate
editor.
Because Kate does not support running multiple servers for the same
language, one needs to use the ``python-lsp-server`` (pylsp) tool.

## Summary
This PR adds symbols introduced by `match` statements.
There are three patterns that introduces new symbols:
* `as` pattern
* Sequence pattern
* Mapping pattern
The recursive nature of the visitor makes sure that all symbols are
added.
## Test Plan
Add test case for all types of patterns that introduces a symbol.
## Summary
This PR adds definition for augmented assignment. This is similar to
annotated assignment in terms of implementation.
An augmented assignment should also record a use of the variable but
that's a TODO for now.
## Test Plan
Add test case to validate that a definition is added.
## Summary
As suggested by @MichaReiser in
https://github.com/astral-sh/ruff/pull/12886#pullrequestreview-2237679793,
this adds an exemption to `RUF027` for `fastAPI` paths, which require
template strings rather than eagerly evaluated f-strings.
## Test Plan
I added a fixture that causes Ruff to emit a false-positive error on
`main` but no longer does with this PR.
Extend the `UseDefMap` to also track which constraints (provided by e.g.
`if` tests) apply to each visible definition.
Uses a custom `BitSet` and `BitSetArray` to track which constraints
apply to which definitions, while keeping data inline as much as
possible.
## Summary
This PR is a pure refactor to simplify some of the logic for `RUF027`.
This will make it easier to file some followup PRs to help reduce the
false positives from this rule. I'm separating the refactor out into a
separate PR so it's easier to review, and so I can double-check from the
ecosystem report that this doesn't have any user-facing impact.
## Test Plan
`cargo test -p ruff_linter --lib`
## Summary
This PR adds support for adding symbols and definitions for function and
lambda parameters to the semantic index.
### Notes
* The default expression of a parameter is evaluated in the enclosing
scope (not the type parameter or function scope).
* The annotation expression of a parameter is evaluated in the type
parameter scope if they're present other in the enclosing scope.
* The symbols and definitions are added in the function parameter scope.
### Type Inference
There are two definitions `Parameter` and `ParameterWithDefault` and
their respective `*_definition` methods on the type inference builder.
These methods are preferred and are re-used when checking from a
different region.
## Test Plan
Add test case for validating that the parameters are defined in the
function / lambda scope.
### Benchmark update
Validated the difference in diagnostics for benchmark code between
`main` and this branch. All of them are either directly or indirectly
referencing one of the function parameters. The diff is in the PR description.
This adds the `fast-api-unused-path-parameter` lint rule, as described
in #12632.
I'm still pretty new to rust, so the code can probably be improved, feel
free to tell me if there's any changes i should make.
Also, i needed to add the `add_parameter` edit function, not sure if it
was in the scope of the PR or if i should've made another one.
If a builtin is conditionally shadowed by a global, we didn't correctly
fall back to builtins for the not-defined-in-globals path (see added
test for an example.)
