docs(docker): document ccs-net contract for sibling containers (#1259)

Add "Connect your app to CLIProxy" section to docker/README.md with:
- Public contract table (network=ccs-net, service DNS=ccs, ports 8317/3000)
- Pattern A: same compose file with external network reference
- Pattern B: docker run --network ccs-net
- Troubleshooting subsection (DNS, missing network, conflict, Podman, MTU)

Add one-line link in README.md pointing to the new section.
Add CHANGELOG entry under Unreleased noting the contract as SemVer-major stable.
Add CONTRIBUTING.md note that changing services.ccs or networks.ccs-net requires major bump.
