 * A selection strategy: given changed files, decide which specs must run.

 * "I can't scope this — run everything." The {@link selectImpactedTests} pipeline
 * unions scoped results and lets broad win (fail-open). Implementations:
 * `CoverageMapStrategy` (runtime coverage), and — later — an AST selector for
 * test-internal changes and a dep-graph selector for dependency changes.
