The built hacked binary segfaults on Linux the moment a native GTK3 dialog (file/folder browse) opens while a GLFW/OpenGL context is live: sqweek/dialog's Linux backend never calls XInitThreads() before gtk_init(), and GLFW's own X11 backend installs a process-wide Xlib error handler that collides with GTK's. Vendor a pinned copy of github.com/sqweek/dialog (New BSD) into modding/sqweek-dialog/ so it can be patched like every other vendored source here: sqweek-dialog-patches/01-xinitthreads.patch adds the missing XInitThreads() call, and hacked-patches/01-use-patched-dialog.patch adds a go.mod replace directive pointing hacked's own sqweek/dialog dependency at that local copy. build-hacked.sh now stages both hacked/ and sqweek-dialog/ into a scratch modding/build/ directory and applies their patch series before compiling, rather than building hacked/ in place; .gitignore picks up that new scratch directory. Also expand modding/README.md: number its existing sections and add a worked "Example: Editing a message" walkthrough covering Static World Data, the Messages window's clipboard-only text editing, saving the Mod Location, and the absolute-path requirement for run.sh's mod-folder argument.

/* launching dialogs within the event loop like this has
|
|
** a serious problem in practice. On Linux/Windows the
|
|
** dialog is not modal, which means events on the main
|
|
** window still get queued up.
|
|
**
|
|
** But the dialog functions are synchronous, so we don't
|
|
** process any of these events until the dialog closes. End
|
|
** result is if the user clicks multiple times they end up
|
|
** facing multiple dialogs, one after the other.
|
|
**
|
|
** For this reason, it is recommended to launch dialogs
|
|
** in a separate goroutine, and arrange modality via some
|
|
** other mechanism (if desired). */
