Merges the fixed-flow change (Planner -> Validator -> Coder -> Validator),
universal per-org-agent self-planning, node-level validator skill, and
frontend dynamic/historical graph asks into one requirements doc, folding
in the P0 resume-artifact bug and the P2 test_script structural-fix
placeholder that were blocking on the same design. Records the user's
2026-08-08 decision to merge all four org stages into one work_graph_run
(scheme A) rather than cross-graph routing (scheme B), plus the concrete
schema conflicts that decision surfaces (work_graph_run.org_node's single
value + unique-active-run index) for Phase 2's SDD to resolve.

work-graph-partial-artifact-persistence and work-graph-self-planning-
and-loop-back (requirements + design) are all shipped and tested;
move them out of docs/todo/ and fix up the docs/todo/*.md and
src/*.py path references that pointed at their old location.
