Phase 5: Rename debug artifacts from run.toml/graph.fabro to
workflow.toml/workflow.fabro. Change write_run_config_snapshot to
byte-for-byte copy of the original TOML instead of re-serialization.
Phase 6: Add run_from_record() that builds execution state directly
from a RunRecord, bypassing prepare_workflow(). Refactor run_command
into run_command + run_command_impl to share execution logic. Simplify
run_engine_entrypoint to call run_from_record() instead of
reconstructing RunArgs and re-parsing the workflow.
Step 7k: Write RunRecord in the API server's execute_run() for
observability, enabling fabro ps/inspect for API-initiated runs.
Fix stale manifest.json reference in docs/agents/outputs.mdx.
