Implements a global `emulators.dataDir` setting in `firebase.json` to allow users to easily persist and re-load emulator data across sessions. Key changes: - Added `emulators.dataDir` to `firebase.json` schema. - Updated `firebase init emulators` to prompt for `dataDir` configuration. - Added `--ephemeral` flag to `emulators:start` and `emulators:exec` to ignore `dataDir` for a single run. - Emulators now automatically import data from `dataDir` on startup if it exists and contains valid export metadata. - Emulators now automatically export data to `dataDir` on clean shutdown if `dataDir` is configured (and not overridden by `--export-on-exit` flag). - Handled deprecation of `emulators.dataconnect.dataDir`, preferring the global `emulators.dataDir` with warnings. - Added unit tests for the new functionality.
