fix(nextjs): add force dynamic exports for new copilot routes (#784)

* feat: use 8-core self-hosted runner for faster Docker builds

* fix: lazy load large YAML prompt to prevent build memory exhaustion

- Convert YAML_WORKFLOW_PROMPT from static export to lazy function
- Prevents 281-line string literal from being loaded during static generation
- Fixes exit code 137 memory exhaustion during Docker builds

* fix(nextjs): add force dynamic for copilot routes to resolve OOM issue
