Pull request overview

Syncs agent/standards documentation and linting entrypoints from the TemplateDotNetTool template into SarifMark to keep repo governance docs and lint workflow aligned with the shared baseline.

Changes:

• Expanded lint.sh / lint.bat to restore dotnet tools and run reqstream, versionmark, and reviewmark lint steps; added PUPPETEER_SKIP_DOWNLOAD.
• Updated AGENTS.md and refreshed standards docs (added coding-principles.md + testing-principles.md, added front-matter metadata, clarified/reshaped several standards).
• Updated the quality agent checklist to include hierarchy boundary checks for tests and reorganized Result guidance.
