Subject: [PATCH] One vocabulary: Knowledge, tools, and connectors in plain
 words

- Sources (the collection) are called Knowledge: the settings page (now
  /settings/knowledge; /settings/sources redirects), the composer and
  agent pickers, Add knowledge, and "syncs into Knowledge" on connectors.
  Citations keep "sources". All seven locales.
- Connector cards describe what they do ("Syncs into Knowledge", "Looks
  things up", "Takes actions") and drop publisher labels ("Built in",
  "Preset"). Filters read "Files & storage" and "Docs & wikis" so
  "knowledge" means one thing.
- Custom tools are tools: "Add custom tool". The agent picker no longer
  splits built-in tools into "Built-in" and "Default".
- Confluence is one card: syncing pages into Knowledge and the Jira &
  Confluence MCP actions (part_of on the preset) share a page. The part
  shows on its own when Confluence sync is not set up.

+**Knowledge** (formerly Sources) is what the assistant searches: uploads, links, and content synced from your connections. The **Add knowledge** and **Add Tool** dialogs, the composer's Knowledge and Tools menus, and the agent builder all start the same flow, and list tools grouped by the connection they use. A service offered two ways appears as one card: Confluence syncs pages into Knowledge and, through **Jira & Confluence**, lets agents search and update Jira and Confluence.
 
 Click a connected card to see its account, the sources and tools that use it, and to **Reconnect** or **Disconnect**. Disconnecting keeps a source's indexed content but stops its sync.
