fix(structure): refresh picks up external schema changes (#1281)

CHANGELOG.md

@@ -37,6 +37,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - AI Chat: Gemini provider now round-trips `thoughtSignature` on function calls, fixing the second-round 400 error after a tool runs.
 - AI Chat: GitHub Copilot tool registration was failing with "Expected string" schema validation errors. Optional fields now register with `type: "string"` instead of `type: ["string", "null"]` and are excluded from `required`, which Copilot's LSP validator accepts.
 - MySQL/MariaDB: `BIT(N)` columns now display as decimal numbers (`0`, `1`, `255`) instead of raw bytes that showed up as control characters like `^A` in the data grid. (#1272)
+- Structure tab: Refresh and ⌘R now show external schema changes immediately. Previously a column renamed from another session stayed stale on the Columns and DDL sub-tabs until the user switched tabs, and the ClickHouse Parts sub-tab ignored Refresh entirely. (#1281)
 - ClickHouse, BigQuery, CloudflareD1, LibSQL, Etcd, and DynamoDB: long-running queries no longer fail at 30 seconds when Settings > Query timeout is set higher. The HTTP transport now uses the configured query timeout plus a 30-second grace, so the server's `max_execution_time` (or equivalent) fires before the client gives up. Setting "No limit" raises the transport ceiling to 1 hour. (#1267)
 - AI Chat: DeepSeek V4 thinking content (`reasoning_content`) is now captured during streaming and passed back in subsequent turns, fixing 400 errors when using deepseek-v4-pro or deepseek-v4-flash.
 - MongoDB: the connection form now shows a Username field. It was hidden for databases where authentication is optional, so connections to auth-enabled servers saved with no credentials and every query failed with "requires authentication" even though the connection looked healthy.
