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

* feat(core): implement PIP-0001 database connection timeout recovery
- Add DbOperationBudget struct for unified execution budget model
- Add deadpool create/recycle timeout for PostgreSQL pools
- Add checkout_postgres_client helper replacing 14 bare pool.get() calls
with timeout + cancel token support
- Fix PostgreSQL TLS cancel: rebuild TLS connector from stored context,
fallback to NoTls on failure
- Add timeout to MySQL kill_query and kill_query_with_opts (5s)
- Extend is_connection_error to match deadpool pool timeout messages
- Unify keepalive default to 30s (was 60s Rust / 0s frontend mismatch)
- Inject PostgreSQL TCP keepalive params (idle=30s, interval=10s, retries=3)
- Inject MySQL tcp_keepalive=30s in OptsBuilder
- Make MySQL inactive_connection_ttl configurable from idle_timeout_secs
- Add stage-based structured logging for pool.checkout/health.check/cancel
- Store PostgresCancelContext in AppState for TLS cancel reconstruction
- Clean up cancel contexts on pool removal/drain
- Add unit tests for DbOperationBudget and pool timeout error detection
* fix(core): align timeout recovery with PIP-0001
* fix(core): handle timeout recovery review issues
* fix(core): complete connection timeout recovery
* fix(core): fall back postgres cancel connector build
* refactor: revert comment translations to English in connection.rs and query.rs
- Revert DbOperationBudget doc comments to English (query.rs)
- Revert PostgresCancelContext and TLS cancel comments to English (connection.rs)
- Keep Chinese error-matching strings in is_connection_error unchanged

* 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
