Configure integrated Gambit from the mirror's gerbil-patches branch,
record that tracking branch in .gitmodules, and update the submodule
pointer to ea114fc3d2f120abbe20393c1f9aeafdd3f8c89f.

That commit invalidates stale stack-overflow undo metadata when
continuations are captured or replaced, preserving saved stack frames
across thread switches. The fix and its regression are published at:
mighty-gerbils/gambit@ea114fc3d2

Validation: configure shell syntax and the exact three-file diff; Gambit's
new test12 fails with the original header and passes with the patch.
An instrumented version of the correction passed 150 fresh-process
16-case Host runs plus a full 39-case run that exercised the protected
transition with the earlier boundary guard disabled.
