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

+# Deploy
+
+## Environments
+
+### Dev (`/deploy dev`)
+```bash
+bash .claude/skills/deploy/deploy_dev.sh
+```
+Builds and restarts the service on the dev server (ubuntu).
+
+### Prod (`/deploy prod`)
+Prod deploy requires being on `master`. Steps:
+1. Ensure all changes are committed and pushed to `master`
+2. Run:
+```bash
+bash .claude/skills/deploy/deploy_prod.sh
+```
+
+`deploy_prod.sh` will:
+- Pull latest code on ubuntu build host
+- Build `linux/amd64` Docker image and push to registry
+- SSH into ECS: stop old container, start new one with `-env=prod`
+
+## Quick Reference
+
+| Target | Command | Branch required |
+|--------|---------|-----------------|
+| Dev    | `bash .claude/skills/deploy/deploy_dev.sh` | any |
+| Prod   | `bash .claude/skills/deploy/deploy_prod.sh` | `master` or `main` |
+
+## Common Mistakes
+
+- Running `deploy_prod.sh` on a feature branch → script guards against this (exits with error)
+- Forgetting to merge/push before deploy → ubuntu build host pulls from remote, so local-only commits won't be included
+- Prod logs go to `/app/logs/app.log` inside the container, not stdout — use `docker exec doc_ai tail -f /app/logs/app.log` on ECS to tail them
