Comprehensive cleanup to align repository with TemplateDotNetTool patterns. Removed incorrectly added CHANGELOG.md (changes are documented via build notes), simplified bloated build/lint scripts to match template, cleaned up configuration files to use proper AGENT_REPORT_*.md naming convention, fixed duplicate workflow steps, and resolved linting issues.

Additional Notes

Changes Made:

1. Removed CHANGELOG.md - Repository uses build notes system for change documentation
2. Simplified build/lint scripts - Replaced bloated versions (210 lines removed) with clean TemplateDotNetTool template versions
3. Cleaned configuration files - Removed bogus ignore patterns (-review-report.md, CODE_QUALITY_REPORT.md, DOCUMENTATION_REVIEW.md) that were created when agents didn't follow AGENT_REPORT_.md naming convention
4. Fixed build.yaml - Removed duplicate "Download integration test results" step (already covered by test-results pattern)
5. Removed duplicate patterns - Cleaned up duplicate node_modules/** entry in markdownlint config
6. Fixed lint issue - Added "slnx" to spell check dictionary to recognize the new solution file format

All 117 tests pass. Build succeeds with 0 warnings, 0 errors. All linting passes (cspell, markdownlint, yamllint, dotnet format).
