* Feat: Add PostgreSQL transfer ownership preview and resolution
- Add ownership policy support for data transfers: preserve, skip, and reassign missing owners
- Preview missing PostgreSQL roles before creating target schema objects
- Show ownership confirmation dialog when target roles are missing
- Allow users to skip ownership changes or reassign missing owners to the target connection user
- Add Tauri and HTTP API support for ownership preview
- Apply ownership statements according to selected policy during PostgreSQL transfers
- Add Chinese localization for ownership confirmation UI
* Feat: Add ownership confirmation localization
- Add ownership confirmation messages for supported desktop locales
- Include skip and confirm labels for ownership handling
- Update transfer test requests to use Preserve ownership policy
Add db.coll.stats() / dataSize() / storageSize(scale) / totalIndexSize()
so these MongoDB shell commands return a result grid instead of the
"Use MongoDB shell-style commands" error (issue #2529).
- backend: collStats via mongo_driver.collection_stats, wired through
mongo_ops, the dbx-web /mongo/collection-stats route, the tauri
mongo_collection_stats command, and the MCP data bridge
- node-core: parseMongoCollectionStatsCommand + result formatter and
executeQuery dispatch (web build + MCP path)
- desktop: mirror the parser/executor/autocomplete in mongoShellCommand.ts,
queryStore.ts, api/tauri/http facade, and mongoCompletion.ts
- tests for the parser, result formatter, and completion entries
Close#2529
* docs: add query result streaming export design
* feat(core): stream query result exports
* feat: expose query result streaming export APIs
* feat(desktop): stream query result exports from grid
* fix: route query result export cancellation through its command
* fix: reduce query export batch size and cancel latency
* opt: del local test files
- Use synchronous pool removal in desktop disconnect_db to prevent
race condition when user quickly disconnects and reconnects
- Rename recordMetadataLoadError to recordConnectionLostError and
export it for cross-store reuse
- Sync query execution errors back to connection state via
recordConnectionLostError in queryStore catch blocks
- Add backend check_connection_health method (dbx-core) with Tauri
command and web route for proactive pool verification
- Add frontend checkConnectionHealth API (tauri.ts/http.ts/api.ts)
- Enhance ensureConnected to verify backend pool health before
assuming connection is valid, auto-reconnect if stale
