vBilling v0.2: durable ledger, Stripe and Metronome, every tenancy model - #1

vBilling v0.2 core:
- Hash-chained ledger with atomic window commits, per-destination cursors,
dead letters with replay, and ingest deduplication.
- Delivery to Stripe Billing Meters, Metronome, Lago and a signed
CloudEvents webhook, with deterministic event IDs.
- Metering for shared nodes, dedicated nodes, and tenant clusters with
their own nodes (vCluster Private Nodes, Auto Nodes, Standalone), read
through a read-only tenant kubeconfig. MIG, time-slicing, GKE partitions
and DRA; deletion watches; fair metering of downtime.
- Prometheus: DCGM utilization including MIG instances, PromQL-defined
billable metrics, auth headers, and a vCluster Platform preset.
- Reconciliation, billing-state enforcement, ingest API and dashboard.
Fixes from a run on GKE with L4 and A100 GPUs and a Stripe sandbox:
- Find Stripe customers by listing them where search is unavailable.
- Count physical GPUs once under MIG and fall back to engine activity.
- Record GPUs that are installed but not allocatable as downtime.
- Add the {{window_seconds}} template and trim secrets read from files.
The chart runs vBilling as a StatefulSet with a ledger volume, a Service, RBAC that only grows with the features enabled, the suspension admission policy, a ServiceMonitor, and Secrets or existingSecret for every key. The Lago demo now generates its RSA signing key at runtime.
examples/gke-gpu goes from an empty project to Stripe invoices: a time-sliced L4 tenant cluster, an A100 joined as a private node with the GPU Operator and MIG, DCGM through Prometheus, and vBilling in Stripe test mode. The docs site gets the example page, troubleshooting for private nodes and DCGM, and quick starts that keep keys in Secrets.
CI runs vet, race tests and a Helm lint on every pull request. Publishing a release builds the linux/amd64 and linux/arm64 image the chart defaults to and attaches the packaged chart.
