feat: add agentic presets and preset-level reset (Phase 3)

Adds three new presets demonstrating the LLM Runtime Modifier:
- Support Chatbot / Chatbot → L2 (generative output)
- RAG Knowledge Assistant / RAG-Wissensassistent → L3 (tool use)
- Coding Agent / Coding-Agent → L4 (agentic)

Clicking any preset now sets llmRuntimeLevel explicitly (defaulting
to 0 for legacy presets via `?? 0`), so switching between classical
and LLM-integrated presets resets the modifier correctly. The active
state also compares levels to prevent false-positive highlights.
