Integrations Hub & Knowledge Base Expansion

Features

• MCP Integrations Hub — New dedicated integrations page with provider grid, connect/disconnect flow, and tool explorer for managing all your data sources.
• Knowledge Base Providers — Added Slack, Confluence and Jira, Linear, HubSpot CRM, and Dropbox as knowledge base connectors via MCP, alongside Notion.
• Category Management — Conditional category picker on the Data Hub — one-time selection if unlocked, read-only display once locked.
• Changelog Page — Public changelog at /changelog with version sidebar, animated transitions, and markdown content.

Improvements

• Model Logo Stack — Overlapping model logos display more cleanly.
• Integration Card Design — Redesigned cards with brand-forward logos, atmospheric depth effects, and category sections.
• Bento Grid Layout — Refreshed integrations overview with a modern bento grid replacing the old WordPress/GitHub UI.
• Sidebar Reorganization — Moved Integrations under Knowledge Base category in the sidebar, removed standalone filter pills.

Fixes

• Grok Logo — Switched from the xAI corporate logo to the actual Grok LLM logo on model cards.
• Avatar Stack Overflow — Bumped display limit from 8 to 10 so all models show without a "+1" badge.
• Improve Page Overlap — Fixed sidebar overlap on the Improve page.
• Category State — The category lock now updates as soon as you change categories.
