feat(P33): uptime-kuma primitive + deploy-uptime pipeline stage (REQ-88..91)

---ci---
project: acdl
phase: 33
milestone: v1.8
status: execute
---/ci---

- New uptime L1 primitive (aws:ecs:uptime-service) deploying uptime-kuma
  on ECS Fargate with feature_flag_enabled, monitored_endpoints,
  static_checks, alert_channels (Teams/email/SMS/GitHub issues).
- Adapter emits ECS Fargate task + service when feature_flag_enabled=true;
  emits nothing when false. Container image louislam/uptime-kuma:1.
- New deploy-uptime pipeline stage in pipelines/deploy.yaml (after
  publish-outputs, before comment-outputs). Now 9 stages.
- run_platform.sh --deploy-uptime flag + automatic uptime deployment
  after L2 module (separate state $WORK/uptime-tf). Endpoints from L2
  outputs passed as monitored_endpoints. Feature flag from
  inputs.uptime_enabled (default true).
- scripts/seed_uptime_monitors.py for post-deploy monitor seeding via
  uptime-kuma API.
- Registered in registry.json (14 modules total).

Tests: +6 (312 -> 318). All pass.
