研究方向

The issue requests replacing heuristic feature detection in gdbgui with the gdb MI command ` list feature`. The reference links to the GDB documentation for this command. A contributor should locate the code in gdbgui that currently guesses features (likely in the backend or the part that communicates with gdb) and replace it with a call to ` list feature`. The solution should parse the response correctly and update feature flags accordingly. Since the repository is no longer under active development, a newcomer should be aware of this and consider if the change is still desired.
