/**
 * The helpers are NOT inlined into every command. Re-sending ~14KB of helper code
 * with each evalScript both wastes the 200ms-polling pipe and — observed on
 * Premiere 26.2.2 — can hit "InternalError: Stack overrun" once the long-lived
 * ExtendScript engine has degraded, at which point every tool call dies with an
 * opaque "EvalScript error.". Instead the file bridge writes the helpers to
 * <tempDir>/helpers_<version>.jsx once, and each command carries only a tiny
 * bootstrap that $.evalFile's them into the engine if this exact version isn't
 * loaded yet. Self-healing across engine restarts, and each version of the server
 * loads its own helpers file, so upgrades can't execute stale helpers.
