- VS Code extension: - Add module symbol table viewer using [Tabulator](https://tabulator.info/) for sorting and formatting rows. - Add context menu action to the modules tree. - lldb-dap - Add `DAPGetModuleSymbolsRequest` to get symbols from a module. Fixes #140626 [Screencast From 2025-08-15 19-12-33.webm](https://github.com/user-attachments/assets/75e2f229-ac82-487c-812e-3ea33a575b70)
