test(dream): conform dream-dir-source-stamp to canonical PGLite isolation pattern

check:test-isolation R3/R4 flagged the new test file: engine was created
in beforeEach (outside beforeAll) and never disconnected in afterAll.
Switch to the canonical shared-engine pattern (beforeAll create,
beforeEach resetPgliteState, afterAll disconnect) per
test/helpers/reset-pglite.ts.
