2026-09-01 (memory allocator & online walls) - added probes for VirtualQuery, AllocateMainDirectMemory, and NpCppWebApi (D284)

Added hardware measurement probes in obSCEne to unblock sibling emulator orbistoun on commercial title walls (recorded in orbistoun D436: PPSA25872, PPSA02664, PPSA03416, PPSA28061):

• include/obscene/platform.h & src/probe/imports.c: Declared and registered sceKernelVirtualQuery and sceKernelAllocateMainDirectMemory under libkernel.
• src/probe/sections/memory.c:
  • 020-memory/virtual-query-mapped: Queries mapped direct memory, dumps the raw SceKernelVirtualQueryInfo buffer via obs_report_written against 0xAA poison pattern to reveal the true struct layout (protection, memoryType, flags, name).
  • 020-memory/virtual-query-text: Queries executable code segment, dumping the layout for RX permissions.
  • 020-memory/virtual-query-stack: Queries thread stack address, dumping the layout for stack mappings.
  • 020-memory/virtual-query-unmapped: Queries 0x720000240000 (the exact address from D436) to record the exact return code and error semantics on unmapped pages.
  • 020-memory/allocate-main: Calls sceKernelAllocateMainDirectMemory, records the reported physical base address, maps it, verifies read/write, and releases it.
• src/probe/sections/layoutmap.c:
  • 138-layout/np-cpp-webapi: Probes libSceNpCppWebApi.sprx, measures Common::initialize address and queries the unnamed online leaderboard NID 0xa9721c01ca796f63.

Verified: make check, make payload injector HARDWARE=1, and bash scripts/verify.sh pass 100% clean.
