fix: Add empty list checks and enhance docstrings (PR #243 review fixes)

Browse Source 
Two critical improvements from PR #243 code review:

## Fix 1: Empty List Edge Case Handling

Added early return checks to prevent creating empty index files:

**Files Modified:**
- src/skill_seekers/cli/unified_skill_builder.py

**Changes:**
- _generate_docs_references: Skip if docs_list empty
- _generate_github_references: Skip if github_list empty
- _generate_pdf_references: Skip if pdf_list empty

**Impact:**
Prevents "Combined from 0 sources" index files which look odd.

## Fix 2: Enhanced Method Docstrings

Added comprehensive parameter types and return value documentation:

**Files Modified:**
- src/skill_seekers/cli/llms_txt_parser.py
  - extract_urls: Added detailed examples and behavior notes
  - _clean_url: Added malformed URL pattern examples

- src/skill_seekers/cli/doc_scraper.py
  - _extract_markdown_content: Full return dict structure documented
  - _extract_html_as_markdown: Extraction strategy and fallback behavior

**Impact:**
Improved developer experience with detailed API documentation.

## Testing

All tests passing:
- ✅ 32/32 PR #243 tests (markdown parsing + multi-source)
- ✅ 975/975 core tests
- 159 skipped (optional dependencies)
- 4 failed (missing anthropic - expected)
