feat: B7阶段3 NVMe MSI/MSI-X中断驱动化 + IDT向量分配器 + 幽灵CQE防御

Browse Source 
- nvme.drv: MSI-X表项编程 + 动态向量(0x40-0xDF池) + 完成槽+irqsave自适应轮询混合模型 + CID校验防御幽灵CQE(BUG-20260803-010) + g_cid跳0 + handler自写LAPIC EOI
- IDT: 向量分配器(bitmap+ctzll, O(1)) + irq_vector_alloc/free (kernel_api尾部追加)
- FUCK: apic_route=1 (生产配置启用IOAPIC->LAPIC接管)
- LESSONS_LEARNED: B7阶段3经验教训(向量分配器/MSI编程顺序/混合轮询/幽灵CQE)
- Bug记录: BUG-20260803-010 (QEMU MSI-X unmask边界幽灵CQE)
