fix: restore Python 3.11 support and stop ty failing CI on warnings (#898)

Two independent root causes had kept main red since 2026-07-05.

Renovate bumped numpy to >=2.5.1. numpy 2.5.0 dropped Python 3.11 wheels entirely (2.5.1 declares requires_python >=3.12; 2.4.6 declares >=3.11), which contradicts this project's own requires-python >=3.11 and its 3.11-3.14 CI matrix, so uv could not resolve on any runner. Reverting the pin restores what commit 4ad79c3 had deliberately established before Renovate undid it, and a renovate.json packageRule now prevents the same regression.

The same Renovate commit bumped ty from 0.0.51 to 0.0.57, which exits non-zero on warning-only output. pyproject.toml deliberately downgrades seven rules to warn, with comments explaining why (llama_cpp is an optional dependency; onnxruntime ships incomplete stubs). Passing ty's own --exit-zero-on-warning restores that intent. Error-level diagnostics still fail the build.
