~/.gsd/defaults.json shadowing is now diagnosed instead of silent — in any project with a .planning/config.json, global model-side keys (model_profile, model_overrides, models, dynamic_routing, runtime, …) were silently ignored for model resolution; a file named defaults.json applied to no real project with no signal. GSD now prints a one-time stderr warning naming the shadowed keys. Resolution precedence is unchanged; global effort keeps working via effort sync and never warns. (#3532)
