feat(runner): add resource limits and assertions - #56
Conversation
Allow `TestCase` to override global CPU and memory limits using `SubjectCPULimit` and `SubjectMemLimit`. Add `ExpectResources` to `FleetConfig` to assert on `DeviceResource` gauges (e.g., cpu.container) with exact values or ranges via the new `ResourceBound` type. Implement `fleetWaitResources` to poll for conditions during fleet tests.

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The change adds per-case CPU and memory limits that can override operator-provided ceilings, and some specialized runs may record metadata that does not match the limits applied. This is a bounded resource-control and result-correctness risk requiring owner awareness, but it is not shown to be merge-blocking. Sequence Diagram(s)sequenceDiagram

Centralize the assignment of SubjectCPULimit and SubjectMemLimit in saveResult to ensure all run paths consistently record limits. This ensures that case-pinned limits take precedence over CLI flags and prevents runs from being recorded as unconstrained when they were actually restricted.
