test(ingest): SQL connector + load-bearing + golden, detach-proven (I4)

Browse source 
New: test_ingest_sql.py (connector mechanics + typed rendering + dispatch), test_ingest_sql_loadbearing.py (SQL seams: typed-NULL, typed-REAL, navigability via unchanged okf), test_ingest_golden_sql.py + examples/ingest-golden-sql/ (byte-frozen sqlite golden; NULL->empty, 4200.0->4200.0 and escape discriminate a typed impl from naive ones). Updated: sql-source refusal test repointed to http (I6); manifest schema-breadth comment. Each new seam proven RED at its detach point.
