Description
Problem
pylance ships abi3-only wheels, which free-threaded CPython (3.13t/3.14t) can't load, so it can't be installed there.
Proposal
Keep the abi3 wheels as they are and additionally publish a cp314t wheel. Purely additive, nothing changes for regular CPython users.
This looks low-lift: pyo3 0.28 (already in tree) supports free-threaded builds and handles the abi3 flag automatically, so current main already builds a working cp314t wheel with no code changes. A quick spike confirmed it builds, imports with the GIL off, and holds up under a 16-thread mixed scan/search stress test. pyarrow, numpy, and pydantic-core already publish cp314t wheels.

Research direction
Start by tracing the existing abi3 wheel publishing workflow and the pyo3 0.28 build configuration; no specific files are named in the issue. Done means an additional cp314t wheel is published while abi3 wheels remain unchanged, and the wheel builds, imports with the GIL off, and passes the described mixed scan/search stress test.
