Subject: [PATCH] Do not expose tools for standalone text-only LLMRunner tasks
 (#59)

Removes tool exposure from the standalone `LLMRunner` when `enableTools=false`.

Some standalone text-only tasks, such as L1 extraction, expect plain text output and do not need tool access. Passing even a read-only tool subset can still encourage tool-calling behavior on OpenAI-compatible backends, which makes this path less stable than necessary.

With this change:

- `enableTools=true` keeps the existing sandboxed tool behavior
- `enableTools=false` sends no tools at all
