feat: add Linux aarch64 wheel builds via ubuntu-24.04-arm runner

Adds native Linux ARM64 (aarch64) wheel builds using GitHub's
ubuntu-24.04-arm runner, mirroring how macOS ARM was added in #74.

- Add ubuntu-24.04-arm to the platform matrix in push.yml and release.yml
- Remove explicit archs = ["x86_64"] restriction so cibuildwheel
  auto-detects the native arch on each runner (x86_64 on ubuntu-latest,
  aarch64 on ubuntu-24.04-arm)
- Bump version to 0.7.0.11

All 15 tests pass on linux/aarch64 natively.
