That makes yas-minor-mode active in every buffer, not just prog-mode-derived ones. I added a small helper, `cj/--yas-activate-fundamental-extras`, attached as `:hook (yas-minor-mode . ...)`. It calls `(yas-activate-extra-mode 'fundamental-mode)` so the snippet table at `snippets/fundamental-mode/` is consulted in every buffer regardless of the buffer's own major mode. That's what makes universal triggers like `<cj` work everywhere. The new `tests/test-prog-general-yas-activation.el` covers both wiring (yas-global-mode on, fundamental-mode in yas-extra-modes, yas-minor-mode active in org/text buffers) and end-to-end expansion (the marker snippet expands correctly in fundamental, text, org, emacs-lisp, and python-ts modes). 9 tests, all green; full unit suite green with no regressions.
