Agent Skills: prplos

Use when working with prplOS / prplmesh devices (often WiFi 7 reference platform APs from MaxLinear, Genexis, SoftAtHome). Triggers on "prplOS", "prplmesh", "ubus call WiFi", "TR-181", "amx", "beerocks", "configure AP via console", "WinLab AP", "winlab 的 AP", "AP 設定", "prplos 設定". Covers serial console workflow, TR-181/amx datamodel, network/WiFi configuration, scanning, channel selection, and the non-obvious traps (configure.sh override, hostapd `multi_ap` semantics, default route + MASQUERADE wiped by `gateway_mode`, KeyPassPhrase case sensitivity, killing wld removes the WiFi datamodel).
