feat: Add unlimited local repository analysis and fix 10 critical bugs

Features:
- Add local_repo_path config parameter for unlimited file analysis
- Auto-exclude virtual environments and build artifacts (95% noise reduction)
- Enable comprehensive codebase analysis (50 → 323 files, 546% increase)

Bug Fixes:
- Fix logger initialization error (Issue #190)
- Fix NoneType subscriptable errors in release tag parsing (3 instances)
- Fix relative import paths causing ModuleNotFoundError
- Fix hardcoded 50-file analysis limit
- Fix GitHub API file tree limitation (140 → 345 files discovered)
- Fix AST parser 'not iterable' errors (95 → 0 parsing failures)
- Fix virtual environment file pollution (23,341 → 1,109 file tree items)
- Fix force_rescrape flag not checked before interactive prompt

Impact:
- Code coverage: 14% → 93.6% (+79.6pp)
- Files analyzed: 50 → 323 (+546%)
- Classes extracted: 55 → 585 (+964%)
- Functions extracted: 512 → 2,784 (+444%)
- AST errors: 95 → 0 (-100%)

Tested on JMo Security repository with 345 Python files.
