chore(ci): migrate from macos-13 to macos-15-intel runner

GitHub announced the deprecation of the `macos-13` runner image[^1],
which will be completely removed by December 4th, 2025.

This commit migrates all workflows to use `macos-15-intel` runners
following the announcement's recommendation.

This also uses `ubuntu-latest` alias instead of explicit `ubuntu-24.04`.
