bigtux 771cf6cf50 feat: Add OpenTelemetry OTLP HTTP receiver

- Add POST /v1/traces endpoint for OTLP JSON trace ingestion
- Convert OTLP spans to internal format and save to PostgreSQL
- Manual JSON parsing (no Go 1.24 dependencies)
- Add Node.js instrumentation example with Express
- Add Python instrumentation example with Flask
- Auto-instrumentation support for both languages

Node.js OpenTelemetry Example for Ophion

This example demonstrates how to instrument a Node.js application with OpenTelemetry and send traces to Ophion.

Setup

# Install dependencies
npm install

# Start Ophion server (in another terminal)
# cd ~/projetos_jarvis/ophion && go run cmd/server/main.go

# Run the app with tracing
npm run trace

Environment Variables

Variable	Default	Description
`OTEL_EXPORTER_OTLP_ENDPOINT`	`http://localhost:8080/v1/traces`	Ophion OTLP endpoint
`OTEL_SERVICE_NAME`	`nodejs-example`	Service name in traces
`PORT`	`3000`	App HTTP port

Test Endpoints

# Health check
curl http://localhost:3000/health

# Get all users (generates trace)
curl http://localhost:3000/users

# Get single user
curl http://localhost:3000/users/1

# Create order (complex trace with nested spans)
curl -X POST http://localhost:3000/orders \
  -H "Content-Type: application/json" \
  -d '{"items": [{"id": 1, "qty": 2}]}'

# Trigger error (error trace)
curl http://localhost:3000/error

View Traces in Ophion

# List recent traces
curl http://localhost:8080/api/v1/traces

# Get specific trace
curl http://localhost:8080/api/v1/traces/<trace_id>

How It Works

tracing.js - Initializes OpenTelemetry SDK with OTLP HTTP exporter
Auto-instrumentation captures HTTP requests automatically
Manual spans in app.js add custom business logic traces
All spans are sent to Ophion's /v1/traces endpoint in OTLP JSON format
