fix(ci): lint error and sdk test timeout

[eersnington]

Two fixes for CI on main. Both CI jobs fail on main and on every open PR.

Job	Failure	Fix
packages	pnpm lint: Biome format error in packages/pi/src/runtime.ts (from #351)	Format the file.
checks	Run SDK tests: the first beforeEach times out after 120s	Time out each health request in waitForHealth().

SDK test timeout

waitForHealth() checks its deadline only between requests, and fetch has no timeout. Undici waits up to 300s for response headers.

The first health request to the first container of the run connects, then gets no response. That one request holds beforeEach until Vitest kills it at 120s. Health requests to later containers fail fast with UND_ERR_SOCKET, so the retry loop works for them.

sequenceDiagram
  participant T as beforeEach
  participant C as first container
  T->>C: GET /v1/health
  Note over T,C: Before: no response, the hook waits until the 120s hookTimeout
  Note over T,C: After: aborts at 2s
  T->>C: GET /v1/health (retry)
  C-->>T: 200
