[ATRIwOX]

Summary

• Addons read and write through sumeru/core/sdk. The kernel keeps search, write, copy, defaults, and object actions; modules no longer call the ORM for those.
• Window actions carry target, record, limit, groups, and view bindings. Menus honor active and group removal, and a user's home action opens on login.
• compute=<function> binds a same-package function at generate time and checks the return value against the field type. A selection tagged status is the status bar; its constants are the stages, and a stage click writes that value.

Test plan

• cd sumeru && make
• Open a form whose selection field is tagged status and click a stage; the value saves and the workflow check still runs
• Confirm a module compute registered only by compute=<function> fills the field on read, and a wrong return type fails with the field name in the error
• Sign in as a user with a home action and confirm that action opens
• Confirm a menu restricted by group is hidden for a user outside that group
