Refactor allocator to use offsets instead of absolute pointers

Browse Source 
JLANG_malloc now returns size_t offsets relative to the heap buffer,
making all references stable across heap growth (realloc). Object API
updated accordingly: constructors return offsets, obj_print/obj_free
receive (allocator, offset). Added heap auto-grow when out of space.
