Generate Database Migrations

Generate database migrations for the specified Medusa module.

The user will provide the module name as an argument (e.g., brand, product, custom-module).

For example: /medusa-dev:db-generate brand

Use the Bash tool to execute the command npx medusa db:generate <module-name>, replacing <module-name> with the provided argument.

Report the results to the user, including:

• The module name for which migrations were generated
• Migration file name or location
• Any errors or warnings
• Next steps (running npx medusa db:migrate to apply the migrations)
