Rack middleware that traces every request through all processing layers — controller, ActiveRecord, cache, ActiveJob, and outbound HTTP via Faraday — then emits a flame-graph-style summary to the Rails log. Supports plain-text, ASCII flame-graph, and JSON output; N+1 detection; sampling; path filtering; Sidekiq and ActiveJob adapters; and Rails log tags. Overhead under 1ms per request.
