trace_native_values set one truncated flag for two different facts: the
returned page omits retained nodes, and a budget stopped or narrowed the
traversal. A last page of a complete trace and a node- or edge-capped trace
both reported truncated: true with next_offset null and no unknown naming the
cap, so a caller could not tell whether to follow pages, raise a budget, or
treat the examined graph as exhausted.
Results now carry page_truncated for page omission and a traversal object
that is complete, or truncated with the observed reasons in schema order:
max_depth, max_functions, max_call_sites, max_nodes, max_edges,
node_payload_bytes, provider_pcode_truncated and ambiguous_call_candidates.
truncated keeps its previous meaning as the union of both.
A new budget owner admits nodes and edges and records every cause together
with a located unknown, only after a budget rejects work; an exactly filled
budget is no longer truncation. Depth and ambiguous-candidate limits are
resolved after traversal, so a destination analyzed or queued through a
shallower path is no longer reported as depth-limited. Once an edge is
rejected, remaining call sites in that procedure are not resolved.
