yusyus ea289cebe1 feat: Make EXCLUDED_DIRS configurable for local repository analysis ...

Closes #203

Adds configuration options to customize directory exclusions during local
repository analysis, while maintaining backward compatibility with smart
defaults.

**New Config Options:**

1. `exclude_dirs_additional` - Extend defaults (most common)
   - Adds custom directories to default exclusions
   - Example: ["proprietary", "legacy", "third_party"]
   - Total exclusions = defaults + additional

2. `exclude_dirs` - Replace defaults (advanced users)
   - Completely overrides default exclusions
   - Example: ["node_modules", ".git", "custom_vendor"]
   - Gives full control over exclusions

**Implementation:**

- Modified GitHubScraper.__init__() to parse exclude_dirs config
- Changed should_exclude_dir() to use instance variable instead of global
- Added logging for custom exclusions (INFO for extend, WARNING for replace)
- Maintains backward compatibility (no config = use defaults)

**Testing:**

- Added 12 comprehensive tests in test_excluded_dirs_config.py
  - 3 tests for defaults (backward compatibility)
  - 3 tests for extend mode
  - 3 tests for replace mode
  - 1 test for precedence
  - 2 tests for edge cases
- All 12 new tests passing ✅
- All 22 existing github_scraper tests passing ✅

**Documentation:**

- Updated CLAUDE.md config parameters section
- Added detailed "Configurable Directory Exclusions" feature section
- Included examples for both modes
- Listed common use cases (monorepos, enterprise, legacy codebases)

**Use Cases:**

- Monorepos with custom directory structures
- Enterprise projects with non-standard naming conventions
- Including unusual directories for analysis
- Minimal exclusions for small/simple projects

**Backward Compatibility:**

✅ Fully backward compatible - existing configs work unchanged
✅ Smart defaults maintained when no config provided
✅ All existing tests pass
