feat(deploy): methodology lib and project_orchestrator_path
**Motivations:**
- Keep shared methodology, envs, and future quality sequences in ia_dev; single project orchestrator script per repo
**Root causes:**
- N/A
**Correctifs:**
- N/A
**Evolutions:**
- Add deploy/lib/deploy-methodology.sh (test|pprod|prod validation)
- deploy.sh sources methodology before orchestrator
- orchestrator prefers deploy.project_orchestrator_path then legacy phases/deploy_script_path
- conf.json: project_orchestrator_path for lecoffreio, algo, enso; remove hooks where redundant
- Document in README.md, projects/README.md, deploy/lib/README.md
**Pages affectées:**
- deploy/*, projects/*/conf.json, README files
