feat: add Ansible deployment for MemPalace v3.0.0 fleet integration (#570)

- Add ansible/roles/mempalace/ with tasks, templates, defaults, meta
- Add ansible/playbooks/deploy_mempalace.yml targeting fleet hosts
- Role installs mempalace==3.0.0 in isolated venv
- Deploys mempalace.yaml, MCP config, and session-start wake-up hook
- Mines home + sessions, runs search smoke test, generates wake-up context
- Add tests/test_mempalace_ansible_role.py validating role structure
- Update docs/MEMPALACE_EZRA_INTEGRATION.md with Ansible usage
- Update existing integration test to assert Ansible section present

All 12 mempalace tests pass.

+## Fleet Ansible deployment
+
+Deploy MemPalace to Ezra (or the whole fleet) with the Ansible playbook:
+
+```bash
+ansible-playbook -i ansible/inventory/hosts.ini ansible/playbooks/deploy_mempalace.yml --limit ezra
+```
+
+This playbook:
+1. Creates a dedicated venv and installs `mempalace==3.0.0`
+2. Deploys `mempalace.yaml`, MCP config, and session-start hook
+3. Mines the Hermes home and sessions directories
+4. Runs a search smoke test
+5. Generates the wake-up context file
+
+Set `mempalace_run_mining=false` to skip mining on hosts where the corpus is already populated.
+
 ## Why this shape
 
 - `wing: ezra_home` matches the issue's Ezra-specific integration target.
