Qualify wait states in the coordination graph (CUST-WP-0074-T04)

Task nodes carry wait_kind (external | human | both | unqualified, null
unless wait): the hub field wins, otherwise derived from needs_human and
dependency edges (task-level depends_on, or a workplan dependency row whose
target the task cites). Workplan nodes carry blocked_kind (human | external
| none, null unless blocked). Task-level depends_on becomes a task ->
workplan/task depends_on edge; depends_on edges carry edge_kind commitment
(cyan #0891b2), human gates are marked on the node (humanGate, rose
#be123c). A needs_human=true query / "Needs human" toggle / --needs-human
flag keeps only blocked_kind=human workplans and their human-wait tasks;
the parameter survives in the shareable URL and mode switch like
include_residuals. Fabric stays a read of State Hub.
