feat(tests): add robust mock implementations and expand test coverage for S3 and OPFS storage
- Introduced comprehensive mock for the Origin Private File System (OPFS) in `tests/mocks/opfs-mock.ts`, simulating environment for detailed storage testing. - Added `tests/opfs-storage.test.ts`, containing extensive test cases for `OPFSStorage` operations including metadata, nouns, verbs, and storage status. - Improved S3 mock implementation in `tests/mocks/s3-mock.ts` with better object persistence, validation, and logging to emulate real S3 behavior. - Resolved issues related to metadata, nouns, verbs, and storage usage inconsistencies in mock storage adapters. - Enhanced logging and error handling to aid in debugging and test reliability. Purpose: Improve test completeness and reliability by introducing detailed mocks and extended test cases for S3 and OPFS storage systems.
