refactor: move deploy scripts into .claude/skills/deploy/

- Added deploy skill (SKILL.md) with dev/prod instructions
- Moved deploy_prod.sh, deploy_dev.sh, dev_deploy.sh, speed_take.sh
- Updated settings.local.json: new script paths, git merge/push permissions, auto-deploy hook on merge to master
- Removed dev_deploy.sh and speed_take.sh from .gitignore
