Fix include order in hakmem.c - move hak_kpi_util.inc.h before hak_core_init.inc.h

Problem: hak_core_init.inc.h references KPI measurement variables
(g_latency_histogram, g_latency_samples, g_baseline_soft_pf, etc.)
but hakmem.c was including hak_kpi_util.inc.h AFTER hak_core_init.inc.h,
causing undefined reference errors.

Solution: Reorder includes so hak_kpi_util.inc.h (definition) comes
before hak_core_init.inc.h (usage).

Build result: ✅ Success (libhakmem.so 547KB, 0 errors)

Minor changes:
- Added extern __thread declarations for TLS SLL debug variables
- Added signal handler logging for debug_dump_last_push
- Improved hakmem_tiny.c structure for Phase 2 preparation
