Fix artifact downloads by adding cross-workflow run-id parameters

Problem:
- Artifact downloads were failing with "no matches found"
- downloads/v4 defaults to current workflow run
- Artifacts exist in the 4 triggering workflows, not in release.yml

Solution:
- Extended check-all-workflows job to output run IDs for all 4 workflows
- Added run-id and github-token parameters to all download-artifact steps
- Each download now explicitly fetches from the correct workflow run

Mapping:
- wheels artifacts → wheels_run_id
- wheels-docker artifacts → wheels_docker_run_id
- wstest artifacts → wstest_run_id
- main/flatbuffers artifacts → main_run_id

This enables successful artifact collection from all 4 workflows.
