Add Alibaba Cloud OSSFS mount backend to the JavaScript/TypeScript sandbox SDK, aligning it with the Python SDK implementation. Changes: - Add OSSFS interface to models/sandboxes.ts with full type definitions (bucket, endpoint, version, options, accessKeyId, accessKeySecret) - Update Volume interface to include ossfs as a third backend option - Update volume validation in sandbox.ts to check [host, pvc, ossfs] - Export OSSFS type from index.ts - Add 3 tests: OSSFS volume creation, no-backend rejection, multi-backend rejection Partially addresses alibaba#476 (SDK parity gaps - OSSFS support)

Address Codex review feedback: use `!= null` instead of `!== undefined`
so that JSON-normalized null optionals (e.g. `{ ossfs: null }`) are
correctly treated as absent rather than counting as a specified backend.
Add test case to verify null backends do not trigger multi-backend error.
