docs(scribe): merge soft-delete architecture decision into decisions.md

[mpaulosky]

Summary

Scribe merging the soft-delete architecture decision from the inbox into decisions.md.

Changes

• Merged .squad/decisions/inbox/copilot-soft-delete-architecture.md → decisions.md
• Decision: IsArchived soft delete for Categories and Statuses (user directive 2026-04-15)
• Inbox file deleted after merge

Decision Content

Soft delete (IsArchived flag) chosen over hard delete for Categories and Statuses. When a Category or Status is "deleted" by the user, it should be marked IsArchived = true rather than removed from the database. Cascading behavior: Issues associated with an archived Category/Status retain their association but the Category/Status is hidden from active selection UI.

No production code changes. Squad metadata only.
