Add supervisor deployment with continuous pipeline orchestration

Implements automated supervisor instance deployment that runs scheduled
pipelines using a TigerBeetle-inspired continuous orchestration pattern.

Infrastructure changes:
- Update Pulumi to use existing R2 buckets (beanflows-artifacts, beanflows-data-prod)
- Rename scheduler → supervisor, optimize to CCX11 (€4/mo)
- Remove always-on worker (workers are now ephemeral only)
- Add artifacts bucket resource for CLI/pipeline packages

Supervisor architecture:
- supervisor.sh: Continuous loop checking schedules every 15 minutes
- Self-updating: Checks for new CLI versions hourly
- Fixed schedules: Extract at 2 AM UTC, Transform at 3 AM UTC
- systemd service for automatic restart on failure
- Logs to systemd journal for observability

CI/CD changes:
- deploy:infra now runs on every master push (not just on changes)
- New deploy:supervisor job:
  * Deploys supervisor.sh and systemd service
  * Installs latest materia CLI from R2
  * Configures environment with Pulumi ESC secrets
  * Restarts supervisor service

Future enhancements documented:
- SQLMesh-aware scheduling (check models before running)
- Model tags for worker sizing (heavy/distributed hints)
- Multi-pipeline support, distributed execution
- Cost optimization with multi-cloud spot pricing
