Add --quick and --deep flags for research depth

- quick: 8-12 sources each, faster response
- default: 20-30 sources each (unchanged behavior)
- deep: 50-70 Reddit, 40-60 X for comprehensive research

Adjusts API timeouts based on depth. Cache keys include depth
so different depths are cached separately.
