fix(ptc): generous default timeout for delegation-capable scripts

A program script that calls task/parallel_task runs child agents, each a full
LLM turn (often 30s-minutes), so the 30s DEFAULT_SCRIPT_TIMEOUT_MS silently
times out real dynamic workflows. Default delegation-capable scripts (allowed
tools include task/parallel_task) to 10min; pure compute/search scripts keep
30s. Explicit limits.timeoutMs always wins. Bumps to 4.2.7.
