"""Add tenant_plugin_activation table for per-tenant plugin activation.

Revision ID: 0066
Revises: 0065
Create Date: 2026-07-29

Currently plugins are activated globally. This migration creates a
table for per-tenant plugin activation so that different tenants can
enable/disable plugins independently.
