fix: resolve filament vendor/type across split base presets

WebGuide's filament list dropped presets whose vendor and type came from different ancestors, and looped forever on inherits cycles. Walk the full inherits chain with a path-scoped guard, fill only missing values, and skip presets that still lack vendor or type. Add tests for split-base resolution and validate the real profile tree.
