fix#12132, #14006, #13496, #12375, #12132
The previous idb indexer generated a large number of scattered writes
when flushing to disk, which caused CPU and disk write spikes. If the
document volume is extremely large, the accumulation of write
transactions will cause memory usage to continuously increase.
This PR introduces batch writes to mitigate write performance on the web
side, and adds a native indexer on the Electron side to greatly improve
performance.

## Summary by CodeRabbit
* **New Features**
* Full-text search (FTS) added across storage layers and native plugins:
indexing, search, document retrieval, match ranges, and index flushing.
* New SQLite-backed indexer storage, streaming search/aggregate APIs,
and in-memory index with node-building and highlighting.
* **Performance**
* Indexing rewritten for batched, concurrent writes and parallel
metadata updates.
* Search scoring enhanced to consider multiple term positions and
aggregated term data.
* **Other**
* Configurable refresh interval and indexer version bump.
