test: add regression test framework with basic-crud scenario
Parameterized gtest runner auto-discovers fixtures from 3-expected/*/, builds batch-mode OLR configs, and compares JSON output against golden files. generate.sh validates each fixture against Oracle LogMiner before saving. CI workflows: generate-fixtures (weekly) + run-tests (push/PR).
