Fix Windows numpy build; allow 3.15 test failures

- Skip musllinux and win32 when building numpy (CIBW_BUILD=cp315-*
  matches both win32 and win_amd64; numpy has no pyproject.toml
  constraint after we strip its cibuildwheel config)
- Mark 3.15/3.15t test jobs as continue-on-error so they don't block
  CI (3.15t segfaults on CPython beta, rlcompleter test changed behavior)
- Skip test_opt_out_env_var_disables_patch_even_when_interactive on
  Python 3.15 (upstream fixed the rlcompleter bug this test relied on)
