Overview
Rails integration. Loaded automatically when the gem is required inside a Rails app (Rails::Railtie is defined). It:
(a) auto-inits the SDK from ENV before initializers run,
(b) inserts the Rack middleware so one trace opens per request,
(c) wires ActiveSupport::Notifications subscribers (SQL, controller, cache).
Fully automatic: add the gem + set METRIXWIRE_KEY — no code changes.
