refactor(stk.h, module.c, stk.c): switch deps to exported array and clean up types

- Move stk_dep_t to public header
- Rename stk_set_module_dependencies_fn to stk_set_module_deps_sym
- Change default deps symbol name from stk_mod_dependencies to stk_mod_deps
- Read deps as direct exported stk_dep_t array instead of function call
- Update sentinel check to .id[0] != '\0'
- Default module version to 0.0.0 if not provided or invalid
- Remove deps_func from union in stk_module_load
