Improve Windows-compatible virtual memory behavior for allocation, release, protection, and section mappings.

  • Support partial MEM_RELEASE by splitting allocation metadata around released ranges.
  • Round zero-size free addresses to the allocation’s first page.
  • Allow MEM_COMMIT on mapped allocations while enforcing section protection limits.
  • Validate and consume PAGE_TARGETS_INVALID but do not enforce it yet.
