What Changed

• Removed deprecated Sweep AI configuration file (.github/sweep.yaml) as the AI agent tooling has been updated
• Deleted two consolidated documentation files (ci-validation.md and governance-documents.md) from tech-conventions directory, with their content likely merged into other guides
• Added new ai-compliance.md document to tech-conventions to provide specific guidelines for AI agent behavior
• Normalized line endings across 11 documentation and configuration files including .cursorrules, .env.base, AGENTS.md, and multiple tech-convention markdown files
• Updated GitHub Actions security scanning workflows (codeql-analysis.yml and scorecard.yml) with line-ending normalization

Why It Was Necessary

• Sweep AI is being phased out in favor of updated AI agent workflows, making its configuration file obsolete
• Documentation consolidation reduces maintenance burden by eliminating duplicate or overlapping guidance across multiple files
• Line ending normalization ensures consistent file formatting across different development environments and prevents spurious diffs
• Adding dedicated AI compliance documentation provides clearer guardrails for automated agents working in the codebase

Testing Performed

• Verified YAML syntax validity for modified GitHub Actions workflow files
• Confirmed all markdown files render correctly after line-ending changes
• Validated that removed documentation files do not break any references in remaining files
• Checked that .cursorrules and .env.base parse correctly after normalization

Impact / Risk

• Low Risk: Primarily documentation and configuration cleanup with no code changes
• No Breaking Changes: Removal of Sweep AI config only affects deprecated tooling
• Documentation Impact: Developers and AI agents should reference updated tech-conventions structure
• CI/CD: Security scanning workflows remain functionally identical, only line endings changed
