Sentry Otel Exporter Setup

Sets up the OpenTelemetry Collector with Sentry's exporter to route traces and logs into Sentry projects. Walks through version checking (needs otelcol-contrib 0.145.0+), handles both binary and Docker installations, and generates or modifies collector configs with proper pipeline setup. The automatic project creation feature is handy for multi-service architectures but comes with a quirk: it assigns everything to your first team and may drop initial data during creation. Good attention to detail on environment variable handling, making it clear these are placeholders you fill in yourself. The checklist format and existing config detection save you from configuration conflicts when adding Sentry to an established observability stack.
