## Summary This change continues to resolve #16071 (and continues the work started in #16162). Specifically, this PR changes the code in the parser so that it uses the `OperatorPrecedence` struct from `ruff_python_ast` instead of its own version. This is part of an effort to get rid of the redundant definitions of `OperatorPrecedence` throughout the codebase. Note that this PR only makes this change for `ruff_python_parser` -- we still want to make a similar change for the formatter (namely the `OperatorPrecedence` defined in the expression part of the formatter, the pattern one is different). I separated the work to keep the PRs small and easily reviewable. ## Test Plan Because this is an internal change, I didn't add any additional tests. Existing tests do pass. |

Ruff Python Parser
Ruff's Python parser is a hand-written recursive descent parser which can parse Python source code into an Abstract Syntax Tree (AST). It also utilizes the Pratt parsing technique to parse expressions with different precedence.
Try out the parser in the playground.
Python version support
The parser supports the latest Python syntax, which is currently Python 3.12.
It does not throw syntax errors if it encounters a syntax feature that is not
supported by the target-version.
This will be fixed in a future release (see https://github.com/astral-sh/ruff/issues/6591).
