feat(cli): sync workspace config and rerun artifacts

[KoEkko]

Summary

• Add workspace config refresh/sync APIs and CLI commands so GUI saves can refresh generated config files and sync managed config edits back into parameters.
• Move full-flow rerun cleanup into workspace preparation: delete stale step artifacts, reset home/checklist/runtime parameters, refresh config, and rebuild step workspaces before running.
• Keep run_steps() focused on step execution and refresh config before rerunning a single step.

Commits

• feat(cli): refresh and sync workspace config
  • Adds refresh-config / sync-config CLI commands, service handlers, data-layer parameter/config field mappings, and refresh/sync tests.
• feat(cli): prepare workspace artifacts for rerun
  • Adds rerun preparation to clear stale artifacts and runtime state before full-flow reruns, refreshes config before rerun steps, and updates rerun/formal tests.

Tests

• .venv/bin/python -m pytest test/test_workspace.py test/cli/test_workspace_cli.py test/formal/test_state_machine.py -q
