docs: add merge priority order with security hardening as #1 priority

- Updated roadmap phase status (Phase 4 complete)
- Added merge priority table with PR #28 (security) at top
- Documented that security must merge before new services exposed
- Added deployment command reference

+
+| Priority | PR | Description | Status | Notes |
+|----------|-----|-------------|--------|-------|
+| 🚨 1 | #28 | **Security hardening** (firewall, fail2ban, SSH) | Open | **MERGE FIRST** - protects all other services |
+| 2 | #22 | Matrix bridge dependency fix | Open | Blocks Hermes functionality |

+**Merge vs Phase Execution:**
+- PRs can merge independently (no strict phase ordering for merges)
+- **EXCEPTION:** Security hardening (#28) must merge before any new services are exposed
+- After security merge, deploy with: `nh os switch --flake .#lazyworkhorse`
