fix(scripts): update orchestrator integration to use spawn-pod.sh

- Change from looking for 'agentic-sdlc-orchestrator' command to finding spawn-pod.sh script
- Search for script in multiple locations:
  - /scripts/spawn-pod.sh
  - ./scripts/spawn-pod.sh
  - Relative to installed CLI path
- Call script with CLI-style arguments (--task-id, --branch, --repo, --context-dir)
- Update warning message to reflect script location instead of pip install
- Maintain fallback to standard async delegation if script not found

Fixes interface mismatch between spec-kit and orchestrator scripts.
