feat(tests): replace old test scripts with updated test suite for storage and reporting

- Removed outdated test files: `test-tensorflow-import.cjs`, `test-tensorflow-import.js`, and `verify-package-size.js`.
- Introduced `tests/package-size-breakdown.test.ts` to analyze included npm package files and validate their sizes.
- Added comprehensive tests for storage adapters (`MemoryStorage`, `FileSystemStorage`, `OPFSStorage`, etc.) in `tests/storage-adapters.test.ts`.
- Improved OPFS storage mocking and test coverage for browser and Node.js environments.
- Introduced environment detection tests to ensure correct storage adapter selection.
- Created `STORAGE_TESTING.md` to document storage architecture, test coverage, and guidelines for further improvements.

Purpose: Modernize testing infrastructure and enhance storage system reliability through better test coverage and documentation.
