Hardcoded 10 seconds gdb timeout is too low for some applications

[pianofab]

Describe the bug
Gdbgui has a hardcoded timeout when talking to gdb. See below for the hardcoded value and its location.

To Reproduce
Steps to reproduce the behavior:

1. Web browser view, attach to process
2. Click on 'Fetch source files'
3. Look at middle pane gdbgui output (read-only)
4. See error "No gdb response received after 10 seconds."
5. When this happens, the Thread view is lost. Unclear how to regain it / refresh it.

Expected behavior
The timeout is arbitrarily low so it should be configurable.
The hardcoded constant is: const WAIT_TIME_SEC = 10;
See

gdbgui/gdbgui/src/js/GdbApi.tsx

Line 263 in be95217

const WAIT_TIME_SEC = 10;

Additional context
Installed pipx in a conda environment (miniforge). Installed gdbgui via pipx as recommended.
I have a remote browser under a VPN which may be slower than local; however it should be a supported use case.
Everything else seems to work fine so far.

To work around this issue on a live system with gdbgui installed via pipx, we will need to patch the main.js produced by the compilation of the source file above. (Use pipx list to find the location.)
In my system, it is found under:

/root/.local/share/pipx/venvs/gdbgui/lib/python3.12/site-packages/gdbgui/static/js/main.js

Search for the string:

GDBGUI_OUTPUT))},1e4

Replacing the 1e4 with 3e4 (30 seconds) worked for me.
