Pull request overview

This PR introduces a new chiprouter component intended to “own” the fixed ChIP ingress port and fan out incoming telemetry to multiple downstream subscribers, simplifying local CRE topologies.

Changes:

• Add a new framework/components/chiprouter Go module, container image (Dockerfile), runtime binary (cmd/chip-router), and a CTF Testcontainers component wrapper.
• Update documentation to include the new Chip Router component and add a changeset entry.
• Remove the default value for the compatibility testing CLI buildcmd flag and update dockercompose module dependencies.
