v2.2.0

Added

• Antigravity support: agy plugin install https://github.com/grainulation/grainulator installs the tools, research skills and research agent. mcp_config.json gives Antigravity the MCP server.
• Plugin servers use the project folder the agent shares through MCP roots. Codex and Antigravity start plugins outside the project; the server now asks the agent for its folder instead of relying on a launch argument.
• Agent setup guide rewritten with one tested install per agent (Claude Code, Codex, Antigravity, other MCP agents), a check step, update and remove commands and troubleshooting.

Changed

• Plugin project folder order: GRAINULATOR_WORKSPACE, then the folder the agent shares, then the saved default from grainulator setup. When the agent shares a folder it now takes priority over the saved default. The plugin folder is never used as the project.
• Codex project setup and other MCP agents use npx -y github:grainulation/grainulator#v2.2.0, so no local clone is needed.
