// Estimated resident bytes a model will occupy once loaded (weights plus a
// runtime overhead factor for GPU buffers / compute graphs). A family that
// declares auxiliary resources reports their paths and final resident bytes
// through its loader. The server excludes those paths from weight scans and adds
// the reported bytes without interpreting execution plans or residency policies.
// Returns nullopt
// when the footprint is indeterminate: a model directory holding several GGUFs
// and no model.gguf. The guard must not refuse such a load with a 503 -- the
// loader either rejects the ambiguous directory itself (the spec-driven path
// fails with its "contains N GGUF files" error) or accepts it under a
// family-specific layout the estimator cannot resolve, so the guard skips
// rather than guess.
