Establish mandatory quality gates and document serializer architecture

[Copilot]

Project Documentation and Quality Updates

Based on the review of the repository, recent PR #28 (refactoring serializers), and the current state of the project, here are the completed improvements:

Updates to AGENTS.md

• Add mandatory quality checks section before task completion
  • Code review tool requirement
  • CodeQL security scanning requirement
  • Build and test validation requirement
• Add workflow for completing tasks with quality gates
• Update Development Commands section to include format checking
• Add section on security scanning best practices
• Clarify when to run different quality checks during development
• Update "What AI Agents Should ALWAYS Do" to include quality checks
• Use recursive glob pattern for markdown linting

Updates to ARCHITECTURE.md

• Update serialization layer section with deserialization capabilities
• Document that JUnitSerializer now supports both serialization and deserialization
• Document that TrxSerializer now supports both serialization and deserialization
• Update "Future Considerations" section (deserialization is now implemented)
• Update Design Patterns section with new patterns
• Remove "Recent Improvements" section per feedback (historical activities belong in release notes)
• Fix markdown line length issues for linting compliance

General Improvements

• Update .gitignore to exclude coverage reports and test output directories
• Add pre-commit guidance to CONTRIBUTING.md
• Use recursive glob patterns for markdown linting
• Remove custom CodeQL workflow (repository uses GitHub's default CodeQL setup)

Validation

• Run all quality checks before finalizing
• Verify build and tests pass
• Ensure all documentation is accurate and consistent
• Address all code review feedback
• Fix CI/build failures

Original prompt

Please review the project structure and recent PRs to determine suitable project updates such as:

• updates to the AGENTS.md to ensure quality checks are performed by agents before marking work as complete.
• other updates to AGENTS.md for general improvements and to accommodate any recent changes.
• updates to the ARCHITECTURE.md to accommodate recent updates.
• general improvements to the repository for good practices.

@copilot The Quality Checks job failed because the ARCHITECTURE.md file has issues:
ARCHITECTURE.md:95:121 error MD013/line-length Line length [Expected: 120; Actual: 127]
ARCHITECTURE.md:97:121 error MD013/line-length Line length [Expected: 120; Actual: 173]
ARCHITECTURE.md:98:121 error MD013/line-length Line length [Expected: 120; Actual: 136]

Additionally the CodeQL Security Scanning job failed with the following error:
Error: Code Scanning could not process the submitted SARIF file:
CodeQL analyses from advanced configurations cannot be processed when the default setup is enabled

Please address these issues.

@copilot The Quality Checks job failed because the ARCHITECTURE.md file has issues:
ARCHITECTURE.md:95:121 error MD013/line-length Line length [Expected: 120; Actual: 127]
ARCHITECTURE.md:97:121 err...

Fixed both issues:

1. Wrapped long lines in ARCHITECTURE.md to comply with 120-character limit (lines 95, 97, 98)
2. Removed the custom CodeQL workflow that conflicts with GitHub's default CodeQL setup

The repository will continue to use the default CodeQL setup for security scanning. (bf1650c)
