Claude official connector and more agents

One-click Claude connect via the official connector, Grok and more agents on /mcp, Refer a friend in the menu, and Fathom OAuth.

Claude official connector -- connecting Claude opens the official Unabyss listing in Claude's directory: one click, nothing to paste. Same path in the app, onboarding, and the marketing connect guides (now two steps: connect, then send "Let's setup Unabyss").
Grok, Gemini CLI, Antigravity, and Codex on /mcp -- Grok gets a guided two-step connect dialog; Gemini CLI and Antigravity mint a bearer token with a host-specific setup prompt; Codex uses the same OpenAI-plugin flow as ChatGPT. Login and onboarding show the new agents as greyed-out tiles until after signup.
Refer a friend -- in the avatar menu, above Billing, when the referral program is available to you; jumps to referral rewards on the billing page.
Fathom OAuth -- /connections connects Fathom with native OAuth instead of an API key; legacy connections get a reconnect path and start the first import after OAuth returns.

Error toasts -- problem toasts include a Tell support button that opens chat support in the app.
MCP sign-in -- fewer unnecessary reauthentication prompts when your agent reconnects.
