fix: preserve literal types in focus quoted triples and document tracing (#769)

Browse source 
The triples client returns Uri/Literal (str subclasses), not Term
objects.  _quoted_triple() treated all values as IRIs, so literal
objects like skos:definition values were mistyped in focus
provenance events, and trace_source_documents could not match
them in the store.

Added to_term() to convert Uri/Literal back to Term, threaded a
term_map from follow_edges_batch through
get_subgraph/get_labelgraph into uri_map, and updated
_quoted_triple to accept Term objects directly.
