The start-time seed a caller supplies at startInstance, stored as
WorkflowInstance.context entries and read back as
$context.<name>. Written only at start — a completed effect's
outputs live on the run row and read as $effects, a separate bag.
Each value may be any JSON — a scalar, a GlobalDocumentReference, or
an arbitrary object/array. Scalars and GDRs store as their typed
context entries; anything else stores as one context.json entry.
