fix: resolve all test failures by adding proper test fixtures

All 187 tests now pass (100% pass rate). Fixed tests by ensuring all
module documentation includes required elements:

**Root cause:** The parser requires modules to have:
1. Process tag (_Main process_, _Renderer process_, etc.)
2. At least one content section (Methods, Events, or Properties)

**Changes made:**
- Added process tags to all module test fixtures
- Added Methods sections with sample methods to ensure valid parsing
- Fixed DocsParser.spec.ts (3 tests fixed):
  * should handle module with exported class in multi-package mode
  * should handle process tags correctly
  * should generate correct website and repo URLs

- Fixed index.spec.ts (6 tests fixed):
  * should use multi package mode when specified
  * should parse both API files and structures
  * should include version in parsed documentation
  * should handle multiple API files
  * should find all markdown files in API directory
  * should not find non-markdown files

These were not bugs in the code - they were incomplete test fixtures
that didn't match the Electron documentation format requirements.

Test results: ✅ 187/187 passing (100%)
