Review was skipped due to path filters

⛔ Files ignored due to path filters (1)

Lib/test/test_faulthandler.py is excluded by !Lib/**

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.

Walkthrough

Adds a new internal stdlib module _sysconfig (unconditionally compiled), registers it in the VM’s stdlib initializer map, and exposes a config_vars function that returns a dict with Py_GIL_DISABLED: True.

Changes

Cohort / File(s)	Summary
Stdlib module registration `vm/src/stdlib/mod.rs`	Adds `mod sysconfig;` and registers `"_sysconfig" => sysconfig::make_module` in `get_module_inits()`.
_sysconfig module implementation & re-export `vm/src/stdlib/sysconfig.rs`	Adds new PyO3-backed module `pub(crate) mod sysconfig` annotated `#[pymodule(name = "_sysconfig")]` exposing `config_vars(vm) -> PyDictRef` that returns a dict with `Py_GIL_DISABLED: True`, and re-exports `make_module` via `pub(crate) use sysconfig::make_module;`.

Poem

I nibble bytes where tunnels wind,
A tiny module I designed—
I set a flag, then hop away,
Py_GIL_DISABLED, yes, hooray! 🐇
