chore(ax): AX compliance sweep pass 1 — banned imports and naming 
Replace all banned imports (fmt, encoding/json, path/filepath, strings,
os.Getenv) with core primitives across agentic, brain, ide, and transport
packages. Rename abbreviated variables (cfg→config/agentsConfig) and add
_Good/_Bad/_Ugly test triads to transport_tcp_test.go and prep_test.go.
