feat(wlan): DKM wlan driver framework + net connect/disconnect ABI extension

- wlan.drv: multi-vendor PCI probe (class 02:80; Intel AX2xx/Realtek/Atheros ath9k/Broadcom), registers wireless netdev when real hw present (attest net_wlan)
- scan/connect/disconnect: strict panic skeletons (NETWL-E10/E11/E12) until native chip backends (ath9k first, no fw blob) or linuxguest backend land
- net.h/dkm_shared.h: connect/disconnect appended to dkm_net_api + device_desc (ABI-compatible tail append); net.c dispatch with zero-degrade panic
- QEMU (no wlan card): no netdev registered, attest MISSING exempted by FUCK [attest] as designed
