0.6.1 — 2026-08-09

Rust source directory rename and release pipeline fixes.

_rust/ → _rs/ rename — the Cargo source directory (_rust/) was shadowing the compiled .abi3.so module. Renamed to _rs/ so Python loads the native extension instead of the source directory.
manylinux tag — from manylinux_2_17 to manylinux_2_34 (GitHub runners use glibc 2.39, too new for 2.17).
Linux wheel naming — run maturin build from project root (not --manifest-path) so the wheel is named openremap, not openremap_rust.
abi3 + extension-module — both features required together for stable-ABI binary wheels.
