Subject: [PATCH] test(driver-mongodb): skip MongoDBDriver suite when the
 in-memory binary is unavailable

mongodb-memory-server downloads a real MongoDB binary from fastdl.mongodb.org on
first use. In sandboxed / offline CI that download can fail, which made the whole
monorepo `Test Core` job (pnpm turbo run test) red on unrelated PRs.

Start the in-memory server once at collection time and `describe.skipIf` the
suite when startup fails, so it skips cleanly instead of failing every test (a
throwing beforeAll fails rather than skips). When the binary is available
(normal CI), the suite runs exactly as before.

Verified offline: the suite now skips and `driver-mongodb` test exits 0
(2 files passed | 1 skipped; 38 passed | 37 skipped).
