feat: bundle MCP server in plugin.json

Declare the memory-access MCP server inline in plugin.json so it starts
automatically when the plugin is enabled. Users no longer need to
manually add it to ~/.claude.json or run a setup command.

AWS_PROFILE and AWS_REGION are inherited from the Claude Code session.
