Research direction
The implementation should expose `sqlite3 interrupt()` function. The `libsql` codebase likely has C source files where the SQLite API is wrapped. For synchronous execution, the function can be directly exposed. For asynchronous execution, care must be taken to ensure thread safety. Look for existing patterns in the codebase for wrapping SQLite functions. The header files and implementation in `src/` directory should be examined. No linked PRs or comments provide further guidance.
