Add grafana datasource provisioning and update workflow docs

- Configure grafana to use provisioned datasources instead of UI config
- Add prometheus datasource template managed by ansible
- Create minimal grafana.ini with custom provisioning path
- Move ansible_managed to group_vars (fixes deprecation warning)
- Add Remote Hosts and Git Workflow sections to CLAUDE.md
- Document feature branch workflow with tea CLI for PRs

 4. Use `brew services` or Launch Agents to control services on macos hosts.
 5. Test all changes before applying them - ie with ansible, use a --check --diff run.
 
+## Remote Hosts
+
+This repo is typically edited from a workstation (e.g., gilbert), but services run on remote hosts in the tailnet. Use SSH to explore or check state on remote machines:
+
+```bash
+# Explore config paths on indri
+ssh indri 'ls -la /opt/homebrew/etc/grafana/'
+
+# Check service status
+ssh indri 'brew services list'
+```
+
+Key hosts:
+- **indri** - Mac Mini M1 running services (prometheus, grafana, kiwix, forgejo, borgmatic)
+- **sifaka** - Synology NAS (backup target)
+
+## Git Workflow
+
+Use feature branches for all changes. Do not commit directly to main.
+
+```bash
+# Create a feature branch
+git checkout -b feature/description-of-change
+
+# Make changes, then commit
+git add -A
+git commit -m "Description of change"
+
+# Push and create PR using tea CLI
+git push -u origin feature/description-of-change
+tea pr create --title "Description of change" --description "Details..."
+```
+
+PRs are reviewed and merged via the Forgejo web UI at https://forge.tail8d86e.ts.net.
+
+After creating a PR, offer to open it in the browser with `open <pr-url>`.
