fix: Critical CLI bug fixes for issues #258 and #259

This hotfix resolves 4 critical bugs reported by users:

Issue #258: install command fails with unified_scraper
- Added --fresh and --dry-run flags to unified_scraper.py
- Updated main.py to pass both flags to unified scraper
- Fixed "unrecognized arguments" error

Issue #259 (Original): scrape command doesn't accept positional URL and --max-pages
- Added positional URL argument to scrape command
- Added --max-pages flag with safety warnings (>1000 pages, <10 pages)
- Updated doc_scraper.py and main.py argument parsers

Issue #259 (Comment A): Version shows 2.7.0 instead of actual version
- Fixed hardcoded version in main.py
- Now reads version dynamically from __init__.py

Issue #259 (Comment B): PDF command shows empty "Error: " message
- Improved exception handler in main.py to show exception type if message is empty
- Added proper error handling in pdf_scraper.py with context-specific messages
- Added traceback support in verbose mode

All fixes tested and verified with exact commands from issue reports.

Resolves: #258, #259
