/**
 * Deterministic §3.C(3) process-side projection over ONE tool call's args.
 *
 * Shape-based, tool-name-agnostic: any tool whose args carry a string `command` field (the
 * shell-tool family — "Bash" and renamed/white-labeled shells alike) is projected through the
 * word-face regex; every other tool contributes nothing. Case-sensitive (the faces are lowercase
 * tool/stdlib names; an uppercase variant is not these tools). A gate-blocked call still counts:
 * the signal evidences the TASK CLASS (the model reaching for byte-level work), not execution
 * success — and the misfire cost is bounded by the injection cap.
