feat: Add unlimited local repository analysis with bug fixes (PR #195)

Merges PR #195 by @jimmy058910 with conflict resolution.

**New Features:**
- Local repository analysis via `local_repo_path` configuration
- Bypass GitHub API rate limits (50 → unlimited files)
- Auto-exclusion of virtual environments and build artifacts
- Support for analyzing large codebases (323 files vs 50 before)

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

**Conflict Resolution:**
- Preserved logger initialization fix from development (Issue #190)
- Kept relative imports from development (Task 1.2 fix)
- Integrated EXCLUDED_DIRS and local repo features from PR
- Combined best of both implementations

**Testing:**
- ✅ All 22 GitHub scraper tests passing
- ✅ Syntax validation passed
- ✅ Local repo analysis feature intact
- ✅ Bug fixes from development preserved

Original implementation by @jimmy058910 in PR #195.
Conflict resolution preserves all bug fixes while adding local repo feature.
