docs(gigafactory): consolidate gigafactory docs into docs/gigafactory/

Move ROADMAP_COMPLETION_AUDIT.md, TASKS_TO_COMPLETE.md,
gigafactory-phase3-progress.md and FLEET_CONTROL_PLANE.md under
docs/gigafactory/ so the scattered Gigafactory docs are easy to discover.
Update intra-doc and cross-repo source-of-truth references (fleet README
and types.ts comment) to the new agent-queue/docs/gigafactory/ path.
Pure docs/comment move; no behavior change.
