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

+# Future Enhancement Ideas
+
+This document captures ideas for future improvements to the Materia infrastructure and pipeline orchestration.
+
+## Smart SQLMesh-Aware Scheduling
+
+### Current State
+- Extract pipeline runs on a fixed schedule (daily at 2 AM UTC)
+- Transform pipeline runs on a fixed schedule (daily at 3 AM UTC)
+- No awareness of whether SQLMesh models actually need refreshing
+
+### Enhancement Idea
+Add `materia pipeline check <name>` command that uses SQLMesh's internal scheduler to determine if work is needed:
+
+```bash
+# Check if any models need refresh
+materia pipeline check transform
+
+# Returns:
+# - Exit code 0 if work needed
+# - Exit code 1 if nothing to do
+# - Prints list of models that would be updated
+```
+
+**Implementation:**
+```python
+# src/materia/pipelines.py
+def check_pipeline(pipeline_name: str) -> PipelineCheckResult:
+    """Check if pipeline has work to do without creating a worker."""
+    if pipeline_name == "transform":
+        # Run sqlmesh plan --dry-run locally
+        # Parse output to see what models need refresh
+        # Return list of models + their tags
+        pass
+```
+
+**Supervisor Integration:**
+```bash
+# In supervisor.sh
+if materia pipeline check transform; then
+  echo "Transform has work to do, scheduling..."
+  materia pipeline run transform
+else
+  echo "Transform up to date, skipping"
+fi
+```
+
+---
+
+## Model Tags for Worker Sizing
+
+### Current State
+- All transform pipelines run on the same worker type (ccx22)
+- No way to specify that certain models need more resources
+
+### Enhancement Idea
+Use SQLMesh model tags to hint at resource requirements:
+
+```sql
+-- models/serving/obt_commodity_metrics.sql
+MODEL (
+  name serving.obt_commodity_metrics,
+  kind INCREMENTAL_BY_TIME_RANGE,
+  cron '@daily',
+  tags ['heavy', 'long_running']  -- Supervisor uses this!
+)
+```
+
+**Pipeline Check Enhancement:**
+```python
+@dataclass
+class PipelineCheckResult:
+    has_work: bool
+    models: list[str]
+    tags: set[str]  # Aggregated tags from all models needing refresh
+
+# Check if any heavy models need refresh
+result = check_pipeline("transform")
+if "heavy" in result.tags:
+    worker_type = "ccx32"  # Use bigger worker
+else:
+    worker_type = "ccx22"  # Default worker
+```
+
+**Supervisor Integration:**
+```bash
+# In supervisor.sh
+RESULT=$(materia pipeline check transform --format json)
+
+if [ "$(echo $RESULT | jq -r '.has_work')" = "true" ]; then
+  TAGS=$(echo $RESULT | jq -r '.tags | join(",")')
+
+  if echo "$TAGS" | grep -q "heavy"; then
+    WORKER_TYPE="ccx32"
+  else
+    WORKER_TYPE="ccx22"
+  fi
+
+  materia pipeline run transform --worker $WORKER_TYPE
+fi
+```
+
+**Tag Conventions:**
+- `heavy`: Requires larger worker (ccx32+)
+- `long_running`: Expected to take >1 hour
+- `gpu`: Requires GPU instance (future)
+- `distributed`: Could benefit from multi-node execution (future)
+
+---
+
+## Multi-Pipeline Support
+
+### Current State
+- Only extract and transform pipelines
+- Extract doesn't use SQLMesh scheduling
+
+### Enhancement Idea
+Make extract pipeline also SQLMesh-aware, add more pipeline types:
+
+**New Pipelines:**
+- `dbt`: For dbt models (if we add dbt support)
+- `ml`: For machine learning model training
+- `export`: For exporting data to external systems
+
+**Extract with Scheduling:**
+Instead of fixed schedule, use SQLMesh to track last successful extract:
+
+```sql
+-- models/raw/psd_alldata.sql
+MODEL (
+  name raw.psd_alldata,
+  kind INCREMENTAL_BY_TIME_RANGE,
+  cron '@daily',  -- SQLMesh tracks this!
+  tags ['extract']
+)
+```
+
+Then supervisor checks if extract needs running based on SQLMesh state.
+
+---
+
+## Distributed Transform Execution
+
+### Current State
+- All SQLMesh models run on a single worker
+- Large transforms can be slow
+
+### Enhancement Idea
+For models tagged `distributed`, split execution across multiple workers:
+
+```python
+# Detect heavy models that would benefit from parallelization
+result = check_pipeline("transform")
+
+if "distributed" in result.tags:
+    # Split models into batches based on dependency graph
+    batches = split_execution_graph(result.models)
+
+    # Create one worker per batch
+    workers = [create_worker(f"transform-{i}", "ccx22") for i in range(len(batches))]
+
+    # Execute in parallel
+    with ThreadPoolExecutor() as executor:
+        futures = [
+            executor.submit(run_pipeline_on_worker, worker, batch)
+            for worker, batch in zip(workers, batches)
+        ]
+```
+
+---
+
+## Cost Optimization with Multi-Cloud
+
+### Current State
+- Only supports Hetzner Cloud
+- Provider abstraction exists but not utilized
+
+### Enhancement Idea
+Check spot prices across multiple providers and use cheapest:
+
+```python
+# src/materia/providers/pricing.py
+def get_cheapest_provider(worker_type: str) -> str:
+    prices = {
+        "hetzner": get_hetzner_spot_price(worker_type),
+        "ovh": get_ovh_spot_price(worker_type),
+        "scaleway": get_scaleway_spot_price(worker_type),
+    }
+    return min(prices, key=prices.get)
+
+# In supervisor.sh or materia CLI
+PROVIDER=$(materia provider cheapest --type ccx22)
+materia pipeline run transform --provider $PROVIDER
+```
+
+---
+
+## Observability Enhancements
+
+### Current State
+- Logs go to systemd journal
+- No metrics or alerting
+
+### Enhancement Ideas
+
+**1. Prometheus Metrics:**
+```bash
+# Expose metrics endpoint on supervisor
+curl http://supervisor:9090/metrics
+
+# Example metrics:
+materia_pipeline_runs_total{pipeline="extract",status="success"} 42
+materia_pipeline_duration_seconds{pipeline="transform"} 1234
+materia_worker_cost_euros{pipeline="extract"} 0.05
+```
+
+**2. Alerting:**
+```yaml
+# alerts/pipelines.yml
+- alert: PipelineFailure
+  expr: rate(materia_pipeline_runs_total{status="failure"}[1h]) > 0
+  for: 5m
+  annotations:
+    summary: Pipeline {{ $labels.pipeline }} is failing
+```
+
+**3. Web Dashboard:**
+Simple web UI showing:
+- Current supervisor status
+- Recent pipeline runs
+- Active workers
+- Cost tracking
+
+---
+
+## Self-Healing Capabilities
+
+### Enhancement Idea
+Supervisor automatically handles common failure modes:
+
+```bash
+# In supervisor.sh
+run_with_retry() {
+  local pipeline=$1
+  local max_retries=3
+  local retry_count=0
+
+  while [ $retry_count -lt $max_retries ]; do
+    if materia pipeline run $pipeline; then
+      return 0
+    fi
+
+    retry_count=$((retry_count + 1))
+    log "Pipeline $pipeline failed, retry $retry_count/$max_retries"
+
+    # Exponential backoff
+    sleep $((2 ** retry_count * 60))
+  done
+
+  log_error "Pipeline $pipeline failed after $max_retries retries"
+  # Send alert
+  return 1
+}
+```
+
+---
+
+## Priority Queuing
+
+### Current State
+- Pipelines run sequentially based on schedule
+
+### Enhancement Idea
+Add priority system for pipeline execution:
+
+```python
+@dataclass
+class PipelineConfig:
+    priority: int = 0  # Higher = more important
+
+PIPELINES = {
+    "extract": PipelineConfig(priority=10, ...),  # Highest
+    "transform": PipelineConfig(priority=5, ...),
+    "export": PipelineConfig(priority=1, ...),    # Lowest
+}
+```
+
+Supervisor maintains a priority queue and executes highest-priority work first.
+
+---
+
+## Notes
+- These are ideas for future consideration, not immediate requirements
+- Implement incrementally as needs arise
+- Keep simplicity as a guiding principle
