Replace Copilot container with Runner container

[Copilot]

Renamed the internal container from "Copilot" to "Runner" to better reflect its purpose as a general-purpose command execution environment. The name "Copilot" was misleading since the container is not specific to GitHub Copilot CLI.

Changes

Container Infrastructure

• Renamed containers/copilot/ → containers/runner/
• Container name: awf-copilot → awf-runner
• Image tags: ghcr.io/.../copilot:* → ghcr.io/.../runner:*
• Log directories: copilot-logs/ → runner-logs/

Code

• Type definitions: copilotCommand → runnerCommand, copilotIp → runnerIp
• Function renamed: runCopilotCommand() → runRunnerCommand()
• Docker Compose service: 'copilot' → 'runner'

CI/CD

• Updated .github/workflows/release.yml to build/push runner images
• Updated cleanup scripts for new container name

Documentation

• Updated architecture diagrams and references across all docs
• Preserved references to GitHub Copilot CLI tool (the external tool used within the container)

Breaking Changes

# Old
docker logs awf-copilot
ls /tmp/copilot-logs-*/

# New  
docker logs awf-runner
ls /tmp/runner-logs-*/

Users need to:

• Pull new image: ghcr.io/githubnext/gh-aw-firewall/runner:latest
• Update scripts referencing awf-copilot → awf-runner
• Update log paths: copilot-logs → runner-logs
