fix: restore elb build — import paths, morphology deps, C master declarations header

- Fix wrong ELP import paths in soul.el, elp-input.el, studio.el
  (../foundation/elp/src → ../foundation/el/elp/src)
- Add missing import "morphology.el" to all 29 language morphology modules
- Recompile all affected dist/*.c with correct cross-module declarations
- Add dist/elp-c-decls.h: C-level master forward declarations for ELP package
  (enables elb --force-include to resolve undeclared cross-module calls)
