Address PR feedback: Better samples and realistic search examples

Based on feedback in PR comment, implemented:

Installer improvements:
- Added choice between code/docs sample testing
- Created FSS-Mini-RAG specific sample files (chunker.py, ollama_integration.py, etc.)
- Timing-based estimation for full project indexing
- Better sample content that actually relates to this project

TUI enhancements:
- Replaced generic searches with FSS-Mini-RAG relevant questions:
  * "chunking strategy"
  * "ollama integration"
  * "indexing performance"
  * "why does indexing take long"
- Added search count tracking and sample limitation reminder
- Intelligent transition to full project after 2 sample searches
- FSS-Mini-RAG specific follow-up question patterns

Key fixes:
- No more dead search results (removed auth/API queries that don't exist)
- Sample questions now match actual content that will be found
- User gets timing estimate for full indexing based on sample performance
- Clear transition path from sample to full project exploration

This prevents the "installed malware" feeling when searches return no results.
