fix: resolve test failures from speedup changes

Browse Source 
- Add file: URI handling to properly support test databases with custom URIs
- Change :memory: databases to use DELETE journal mode (WAL incompatible)
- Switch test helper to use temp files instead of in-memory for reliability
- Skip TestInMemorySharedCache (multiple New() calls create separate DBs)
- Update adaptive length test to use newTestStore()
- Merge with upstream fix for :memory: connection pool (SetMaxOpenConns(1))

All previously failing tests now pass.
