Issue Description

The repository lacks comprehensive tool configuration files needed for consistent code quality checks, security scanning, and development practices. Without these configurations, scripts and workflows cannot reference the required settings for spell checking, linting, and security analysis.

Expected Outcome

Complete development tool configurations including spell check dictionaries, markdown linting rules, security scanning configs, and PowerShell analysis settings that enable consistent quality checks across all contributors and CI/CD pipelines.

Files Needed

• .cspell.json and custom dictionaries (.cspell/)
• .markdownlint.json and CLI configuration
• .gitleaks.toml and .checkov.yaml for security
• PowerShell and link check configurations

Additional Context

Priority 1 - Required by scripts (Issues #5, #6) and workflows (Issues #10, #11)
