New fast_tools.py module:
- FastTool base class (matches + run interface)
- RealTimeSearchTool: SearXNG search for weather/news/prices/scores
- FastToolRunner: classifier that checks all tools, runs matching
ones concurrently and returns combined context
Router accepts FastToolRunner; any_matches() forces medium tier
before LLM classification (replaces _MEDIUM_FORCE_PATTERNS regex).
agent.py: _REALTIME_RE and _searxng_search_async removed; pre-flight
gather now includes fast_tool_runner.run_matching() alongside URL
fetch and memory retrieval.
To add a new fast tool: subclass FastTool, add to the list in agent.py.
