## Summary Add cycle handling for `try_metaclass` and `pep695_generic_context` queries, as well as adjusting the cycle handling for `try_mro` to ensure that it short-circuits on cycles and won't grow MROs indefinitely. This reduces the number of failing fuzzer seeds from 68 to 17. The latter count includes fuzzer seeds 120, 160, and 335, all of which previously panicked but now either hang or are very slow; I've temporarily skipped those seeds in the fuzzer until I can dig into that slowness further. This also allows us to move some more ecosystem projects from `bad.txt` to `good.txt`, which I've done in https://github.com/astral-sh/ruff/pull/17903 ## Test Plan Added mdtests. |

py-fuzzer
A fuzzer script to run Ruff executables on randomly generated (but syntactically valid) Python source-code files.
Run uvx --from ./python/py-fuzzer fuzz -h from the repository root
for more information and example invocations
(requires uv to be installed).
