MCP connector tools fixed · selection stays yours · status shown

Fixed a bug where tools from connected apps like Notion or Composio couldn't actually be called during a chat. Connected apps now work the way you'd expect — the AI can see and use their tools. Large tools like Notion's create and update pages now mount properly too.
When you explicitly pick connectors for a chat, only those connectors are used. Other connectors enabled in your space are no longer silently pulled in. Scheduled tasks and bots still automatically pick up every connector enabled in the space, since they can't be reselected each run.
Connector status is now more accurate: if a connector can't be reached, it's marked offline right away and automatically flips back to online once it recovers. The connector picker also shows when it was last checked, with a heads-up if that check is more than a week old.
Retired the built-in PubMed connector. It saw essentially no real usage and could never actually connect.

A task that gets interrupted now keeps retrying automatically until it gets a complete response, instead of leaving you with a cut-off answer.
