feat(supervisor): compute workload manager ( #3114 )
...
Adds the `ComputeWorkloadManager` for routing task execution through the
compute gateway, including full checkpoint/restore support, OTel trace
integration, and template pre-warming.
## Changes
**Compute workload manager**
(`apps/supervisor/src/workloadManager/compute.ts`)
- Routes instance create, snapshot, delete, and restore through the
compute gateway API
- Wide event logging on create with full timing and context
- Configurable gateway timeout, auth token, image digest stripping
**Compute snapshot service**
(`apps/supervisor/src/services/computeSnapshotService.ts`)
- Timer wheel for delayed snapshot dispatch (avoids wasted work on
short-lived waitpoints)
- Configurable dispatch concurrency limit
(`COMPUTE_SNAPSHOT_DISPATCH_LIMIT`)
- Snapshot-complete callback handler with suspend completion reporting
- Trace context management and OTel span emission for snapshot
operations
**OTel trace service**
(`apps/supervisor/src/services/otlpTraceService.ts`)
- Fire-and-forget OTLP span emission for compute operations (provision,
restore, snapshot)
- BigInt nanosecond conversion preserving sub-ms precision for span
ordering
**Template creation**
(`apps/webapp/app/v3/services/computeTemplateCreation.server.ts`)
- Three-mode rollout: required (MICROVM projects), shadow (feature flag
/ percentage), skip
- Integrated into deploy finalize flow
**Shared compute package** (`internal-packages/compute/`)
- Gateway client with namespace-based API (instances, templates,
snapshots)
- Zod schemas for all gateway request/response types
**Database**
- `COMPUTE` variant added to `TaskRunCheckpointType` enum
- `WorkloadType` enum and column on `WorkerInstanceGroup`
- `hasComputeAccess` feature flag
**Env / config**
- Compute gateway URL, auth token, timeout
- Snapshot enable flag, delay, dispatch limit
- Dedicated OTLP endpoint for compute spans
(`COMPUTE_TRACE_OTLP_ENDPOINT`)
