/**
 * Wire each grouped strategy to its data source on the dispatcher /
 * recorder substrate. These are the 4 `enable.*` facades' actual
 * implementations; `RunnerBase.enable` calls them with the right
 * dispatcher / attach handle.
 *
 * Pattern: every facade follows the same shape:
 *
 *   1. Resolve strategy (consumer-supplied OR default)
 *   2. Run `strategy.validate?()` — early-fail on misconfig (New Relic
 *      panel review)
 *   3. Set up subscription / projection
 *   4. Apply per-strategy event-type filter (`relevantEventTypes`)
 *   5. Apply per-call sample rate
 *   6. Wrap calls in try/catch — route errors to `_onError` (passive
 *      recorder rule: never throw to caller)
 *   7. Return Unsubscribe (or handle for lens)
