Adds regression tests for the two non-obvious invariants enforced by the Effect-Drizzle integration: - packages/opencode/test/storage/db-effect.test.ts pins that DatabaseEffect.layer rebuilds a fresh handle after Database.close + dispose, and demonstrates the shared-memoMap poisoning that resetDatabase prevents by disposing every DB-consuming runtime before closing the SQLite handle. - packages/opencode/test/effect/managed-runtime.test.ts pins makeManagedRuntime dispose semantics and the lazy.resetIf compare-and-reset guard so a rebuilt instance is never clobbered by a stale dispose.
