ci(firestore-bigquery-change-tracker): tracker test suites run in no CI workflow

The change tracker's jest suites (including the 52 offline tests added by #2937 that pin the broken-retry-guard fix) run in no CI workflow. Root `jest.config.js` includes only `*/functions/jest.config.js` and gen-schema-view; nothing invokes the tracker package's `test:local`. The regression protection for the shared package both the legacy extension and the kit depend on is invisible to CI.

Fix: add the tracker's offline suites to CI (pattern excluding the live-BigQuery suites, e.g. `insertRetry|backupSettings|clustering|checkUpdates`). Found during the adversarial review of #2937. Related: #3049/#3052 cover kit suites, not this shared package.
