1.13: conditional features python-version predicate ignored, abi3 applied unconditionally

### Bug Description Since maturin 1.13.0, the `python-version` predicate in conditional `[tool.maturin].features` is ignored. The abi3 feature is applied even when the target interpreter does not satisfy the condition, causing a build failure. **pyproject.toml:** ```toml [tool.maturin] module-name = "bencode_rs._bencode" python-source = "py" features = [ { feature = "pyo3/abi3-py311", python-version = ">=3.11" }, ] ``` **Cargo.toml:** ```toml [features] default = [] [dependencies] pyo3 = { version = "0.28.3", features = ['generate-import-lib'] } ``` ### Expected Behavior When running `maturin develop` or `maturin build --interpreter '3.10'` with Python 3.10, the conditional feature `pyo3/abi3-py311` should **not** be enabled (since `3.10 < 3.11`), and a normal `cp310-cp310` wheel should be produced. This worked correctly in maturin **1.12.6**. ### Actual Behavior (maturin 1.13.1) ``` $ maturin develop --uv --no-default-features 📦 Including license file `LICENSE` 🍹 Building a mixed python/rust project 🔗 Found pyo3 bindings with abi3 support 🐍 Found CPython 3.10 at .venv/bin/python 📡 Using build options features from pyproject.toml 💥 maturin failed Caused by: None of the found Python interpreters (CPython 3.10) are compatible with the abi3 minimum version (>= 3.11). Please install a compatible Python interpreter. ``` The `python-version = ">=3.11"` condition is being ignored — maturin applies `pyo3/abi3-py311` unconditionally, then rightfully rejects Python 3.10 as incompatible with abi3-py311. This is a regression in the interpreter resolution refactor (#3032). ### Reproducer 1. Use the `pyproject.toml` / `Cargo.toml` shown above 2. Create a virtualenv with Python 3.10 3. Run `maturin develop` or `maturin build --interpreter '3.10'` Works with maturin 1.12.6, fails with 1.13.0 and 1.13.1. ### Environment - maturin 1.13.1 - pyo3 0.28.3 - Python 3.10 - Ubuntu 24.04 (GitHub Actions) and Windows ### Related - #3028 (previous issue about conditional features + abi3 tags, fixed in 1.12.4) - #3027 (the PR that implemented the fix for #3028) - #3032 (interpreter resolution refactor in 1.13.0, likely regression source)
