feat(scripts): Add automatic UUID generation to ask_sam.sh

**Problem:**
- Agents struggle to generate valid UUIDs and often get it wrong
- Script required conversation ID as first positional argument
- Error messages and validation could be improved
- Duplicate/corrupted code sections
- Default model was set to non-existent 'gpt-5-mini'

**Solution:**
1. **Automatic UUID generation**
   - Uses uuidgen to auto-generate conversation UUID if not provided
   - Optional --uuid flag allows specifying custom UUID
   - Displays generated UUID for reference

2. **Improved argument parsing**
   - All options are now flags (--uuid, --model, --token)
   - More intuitive: ./ask_sam.sh --token xyz 'query'
   - No longer requires conversation ID as positional arg

3. **Better validation**
   - UUID format validation with helpful warning
   - Clearer error messages
   - Fixed duplicate error handling

4. **Code cleanup**
   - Removed duplicate API token validation
   - Fixed cor   - Fixed cor   - Fixed cor   - Fixed cor   - Fixed cor   - Fixed cor   - Fixed cor   - Fixed cor   - ed help text and examples

5. **Enhanced output**
   - Shows conversation UUID and model in summary
   - Better error diagnostics
