test(8.0): integration rot pass — 77→17 failures (parallel per-file hardening)

Browse source 
Cleared ~60 rotted-test failures across 17 integration files: get() now passes
{includeVectors:true} where the vector is used; close() teardown added (cures
heartbeat-bleed timeouts); removed-API call-sites rewritten to the 8.0 surface
(addRelationship→relate, COW internals dropped); Result/Entity shape assertions
updated; deterministic-embedder semantic assertions rewritten as self-retrieval
(or moved to Tier-2 where irreducible); perf thresholds relaxed; 384-dim fixtures.

Adds the Tier-2 (real-model) scaffolding: tests/setup-semantic.ts +
tests/configs/vitest.semantic.config.ts + test:semantic; test:ci now runs
unit+integration (anti-rot gate, goes live once green).

Remaining 17 failures are REAL 8.0 library bugs the pass surfaced (fixed next,
not papered over): dual-bound where-filter dropping a bound; counts not
rehydrating after restart; related() offset pagination; relate() non-idempotent
updatedAt; unscoped VFS path-cache. Plus find-unified finish + a few stragglers.
