Sync template files from TemplateDotNetLibrary

[Copilot]

Binary-copy updated agent, standards, and lint script files from the upstream TemplateDotNetLibrary template.

Changes

New Standards Files

• coding-principles.md — Universal coding principles: literate programming, architecture patterns, anti-patterns
• testing-principles.md — Universal testing principles: hierarchy boundaries (System/Subsystem/Unit), AAA pattern

Updated Standards Files

• csharp-language.md — Now requires coding-principles.md as a prerequisite standard
• csharp-testing.md — Now requires testing-principles.md + csharp-language.md
• design-documentation.md, reqstream-usage.md, reviewmark-usage.md, software-items.md, technical-documentation.md — Minor additions and clarifications from template evolution

Updated Agent Files

• All .github/agents/*.md refreshed; quality.agent.md gains expanded assessment template sections

Updated AGENTS.md

• References new coding-principles.md and testing-principles.md in the standards application section

Updated Lint Scripts

• lint.sh / lint.bat — Restructured with cleaner per-section skip logic and consistent error handling

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Code quality improvement
