TrafficMirror - Real-time production traffic mirroring for staging validation.

Clone live production HTTP/TCP traffic to staging environments in real time with zero
user impact. Validate microservices, detect edge-case regressions, and stress-test
deployments against real-world payloads before rolling out to production.

Features:
  - Non-blocking async packet/request duplication and forwarding
  - Dynamic payload sanitization and PII masking rules
  - Rate-limiting and percentage-based traffic sampling controls
  - Real-time diffing of production vs. staging response telemetry
  - Protocol-agnostic stream mirroring (HTTP/1.1, HTTP/2, gRPC)

Usage:
  $ python main.py --source 0.0.0.0:8080 --target staging.internal:8080 --sample 0.15
  $ python main.py --config /etc/trafficmirror/config.json --daemon
