perf(ci): run Tier A coverage concurrently with isolatedModules ts-jest (#1701)

Tier A coverage runs projects a few at a time (largest first, bounded Jest workers, buffered output, fail-fast kept) and ts-jest transpiles with isolatedModules instead of type-checking per process; five type re-exports become export type, two decorated inputs use import type. Unit Tests and Typechecks job: 26 min -> 9 min (Tier A step 23 min -> 6.5 min).
