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.
