Adds a new AI docs page covering Context Sources: connecting Notion, Linear, Sentry, or a custom MCP server, and attaching them to chats in the Railway Agent and dev.new via the Context picker. Cross-links from the AI overview and Railway Agent pages, and adds a sidebar entry.

Summary
Adds documentation for Context Sources — the feature that lets Railway's agents connect out to external MCP servers and use their tools during a chat.
content/docs/ai/context-sources.md, covering:content/docs/ai.mdandcontent/docs/ai/railway-agent.mdsrc/data/sidebar.ts, generatedsrc/generated/page-urls.jsonupdatedPlacement rationale
This lives under
/ai/alongsiderailway-agent.md, not under/agents.md("Railway for Agents"). Those are the opposite direction:/agents.mdand/ai/mcp-server.mdcover external AI tools (Cursor, Claude Code) calling into Railway viamcp.railway.com. Context Sources is Railway's own agents calling out to Notion/Linear/Sentry/custom MCP servers — the new page calls out this distinction explicitly to avoid confusion between the two "MCP" features.Status note for reviewers
This documents a feature currently gated behind the admin-only
AGENT_CONTEXT_SOURCESflag inrailwayapp/mono. It's marked with the samePriority Boardingbanner pattern already used for other flagged features ahead of GA (seesandboxes.md,feature-flags.md).dev.newitself has no other public docs page yet, so it's introduced here with a one-line description rather than a full product page — worth a second look from whoever owns that launch.Test plan
pnpm install+pnpm dev, confirmed/ai/context-sources,/ai, and/ai/railway-agentall return 200 and render correctly (Banner, links, headings compile through content-collections/MDX without errors)railwayapp/monosource (packages/backboard/src/controllers/workspaces/mcpServers.ts,mcpCatalog.ts,contextIntegrationRegistry.ts, and the frontend settings/chat components)
