Overview

Pure algorithm: Format error details as clean Markdown for LLM debugging

Reads data already stored in ErrorLog — zero runtime cost. Called at display time only. Sections are conditional — only included when data is present.

Examples:

RailsErrorDashboard::Services::MarkdownErrorFormatter.call(error, related_errors: related)
# => "# NoMethodError\n\nundefined method 'foo' for nil\n\n## Backtrace\n\n..."
