ENV Cleanup: Delete Ultra HEAP & BG Remote dead code (-1,096 LOC)

Browse Source 
Deleted files (11):
- core/ultra/ directory (6 files: tiny_ultra_heap.*, tiny_ultra_page_arena.*)
- core/front/tiny_ultrafront.h
- core/tiny_ultra_fast.inc.h
- core/hakmem_tiny_ultra_front.inc.h
- core/hakmem_tiny_ultra_simple.inc
- core/hakmem_tiny_ultra_batch_box.inc

Edited files (10):
- core/hakmem_tiny.c: Remove Ultra HEAP #includes, move ultra_batch_for_class()
- core/hakmem_tiny_tls_state_box.inc: Delete TinyUltraFront, g_ultra_simple
- core/hakmem_tiny_phase6_wrappers_box.inc: Delete ULTRA_SIMPLE block
- core/hakmem_tiny_alloc.inc: Delete Ultra-Front code block
- core/hakmem_tiny_init.inc: Delete ULTRA_SIMPLE ENV loading
- core/hakmem_tiny_remote_target.{c,h}: Delete g_bg_remote_enable/batch
- core/tiny_refill.h: Remove BG Remote check (always break)
- core/hakmem_tiny_background.inc: Delete BG Remote drain loop

Deleted ENV variables:
- HAKMEM_TINY_ULTRA_HEAP (build flag, undefined)
- HAKMEM_TINY_ULTRA_L0
- HAKMEM_TINY_ULTRA_HEAP_DUMP
- HAKMEM_TINY_ULTRA_PAGE_DUMP
- HAKMEM_TINY_ULTRA_FRONT
- HAKMEM_TINY_BG_REMOTE (no getenv, dead code)
- HAKMEM_TINY_BG_REMOTE_BATCH (no getenv, dead code)
- HAKMEM_TINY_ULTRA_SIMPLE (references only)

Impact:
- Code reduction: -1,096 lines
- Binary size: 305KB → 304KB (-1KB)
- Build: PASS
- Sanity: 15.69M ops/s (3 runs avg)
- Larson: 1 crash observed (seed 43, likely existing instability)

Notes:
- Ultra HEAP never compiled (#if HAKMEM_TINY_ULTRA_HEAP undefined)
- BG Remote variables never initialized (g_bg_remote_enable always 0)
- Ultra SLIM (ultra_slim_alloc_box.h) preserved (active 4-layer path)
