Three advanced-API correctness fixes, all reproducible on Node (not Bun-specific):
- Entity/concept extraction returned []. SmartExtractor combined agreeing signals
with a weighted sum compared against an absolute 0.60 gate, so a confident
low-weight signal lost selection to a mediocre high-weight one that then failed
the gate, dropping the whole result. Select and gate on a normalized weighted
average instead. The public `confidence` option now controls the threshold (was
a dead hardcoded 0.60), and the embedding-signal timeout is raised 100ms -> 2000ms
so the neural signal is not silently dropped on slower runtimes.
- Multi-hop find({ connected }) returned only the 1-hop neighbour. executeGraphSearch
ignored depth/via; it now delegates to the depth-aware neighbors() BFS.
- find({ aggregate }) hid groupKey/metrics/count under .metadata, so callers
expecting AggregateResult saw empty rows. Expose those fields at the top level.
Adds real-embedding regression tests in tests/integration/advanced-apis-regression.test.ts.
