chore(framework): disable proposed MCP servers by default

Add "disabled": true on every MCP entry shipped by plugins so they are
visible/documented but inactive until the user opts in. Avoids spawning
third-party processes (playwright, figma, mcp-atlassian) and pushing
placeholder credentials before the user has filled them.
