Orkuncakilkaya 70ab79a4e9 Phase 7b: null literal + x == null (retire ptr_null/ptr_is_null) ... `null` is now a real pointer literal and null-tests are comparisons, instead of `ptr_null()` and `ptr_is_null(x)`: ptr_null() -> null ptr_is_null(x) -> (x == null) not ptr_is_null(x) -> (x != null) Mechanics: a new E_NULL primary (`null`, like true/false) lowers to the `null` pointer; emit_bin's comparison path now picks `ptr` vs `i32` from operand type (via llty), so `==`/`!=` work on any pointer/record/slice. The two intrinsics are deleted. Two reseeds: (A) add the literal + ptr comparison keeping the intrinsics; (B) migrate all 182 call sites (compiler + runtime, via a balanced-paren script that skips string-literal args and rewrites `not ptr_is_null` to `!= null`) and delete the intrinsics. Node/Val/Buf/Tok field defaults now read `ptr = null`. Vocabulary drops the two from LUDIC_INTRINSICS; `null` joins true/false as a language constant (grammar + ludic_syntax.h). LANGUAGE.md notes the literal. Reseeded (21664 lines); C-free fixpoint holds; goldens identical; 17/17; vocab + doc-fences clean.
