feat: improve analyze_code terminal output with non-verbose mode

- Add verbose_output parameter (default: False) to CodeAnalysisRequest
- Modify prepare_code_context to return both full context and summary
- Show only file paths and sizes in terminal by default, not full content
- Full file content is still sent to Gemini for analysis
- Add comprehensive tests for verbose output functionality

This prevents terminal hangs when analyzing large files while still providing
Gemini with complete file contents for analysis.
