Add Claude settings and git workflow guidelines

[amavashev]

Summary

This PR establishes configuration and documentation for Claude-assisted development workflows, with a focus on enforcing native git operations and maintaining code quality standards.

Key Changes

• .claude/settings.json: Added configuration file that:

  • Defines permission allowlist for git operations (add, commit, push, pull, status, diff, log)
  • Denies access to GitHub MCP tools for file operations (create, update, delete, push)
  • Reserves GitHub MCP tools for PR, issue, and Actions management only
  • Includes placeholder fields for attribution tracking

• CLAUDE.md: Added development guidelines documenting:

  • Strict requirement to use native git for all commits and pushes
  • Prohibition on using mcp__github__ tools for version control operations
  • Recommended workflow for commit messages (write to temp file, use git commit -F)
  • Code quality standards (95%+ test coverage requirement)
  • Requirement to maintain AUDIT.md files across server, admin, and client repositories
  • YAML API specs as the source of truth for API definitions

Implementation Details

These files establish guardrails to ensure consistent, auditable development practices when using Claude for code changes, preventing accidental misuse of GitHub API tools while maintaining proper git history and test coverage standards.
