feat(pre-2.1.0): demo data overhaul, examples, migration guides, install script

Pre-2.1.0 adoption polish delivering all four milestones:

A) Demo Data Overhaul — seed_demo.sql rewritten with 35 certs across
   5 issuers, 8 agents, 8 targets, 50+ jobs spanning 90 days, 55+
   audit events, discovery scans, network scan targets, S/MIME cert.

B) Examples Directory — 5 turnkey docker-compose configs:
   acme-nginx, acme-wildcard-dns01, private-ca-traefik,
   step-ca-haproxy, multi-issuer.

C) Migration Guides — migrate-from-certbot.md,
   migrate-from-acmesh.md, certctl-for-cert-manager-users.md.

D) Agent Install Script — install-agent.sh with cross-platform
   support (Linux systemd + macOS launchd), release.yml updated
   for 6-target cross-compilation.

Triple-audited against codebase: 22 factual corrections applied
across docs, examples, and config (env var names, CLI flags, ports,
DNS hook interface, scheduler loop counts, license conversion date).

- **Background Scheduler Monitoring** — 7 background loops run on a fixed schedule:
- Renewal loop: every 1 hour, scans for certificates approaching renewal threshold
- Job processor loop: every 30 seconds, picks up pending/waiting jobs and advances their state
- Health check loop: every 2 minutes, pings agents to detect downtime
- Notification dispatcher loop: every 1 minute, sends queued alerts
- Short-lived cert expiry loop: every 30 seconds, marks expired short-lived credentials
- Network scanner loop: every 6 hours, scans enabled TLS endpoints for certificate discovery
- Digest emailer loop: every 24 hours, sends scheduled certificate digest email to configured recipients
Each loop includes error handling and logs failures via structured slog.

- `GET /api/v1/metrics` — JSON object with gauges, counters, and uptime for custom dashboards
