Fix pre-existing gofmt violations across codebase

[CodeMonkeyCybersecurity]

Problem

gofmt -l . reports 20+ files with formatting violations. These are pre-existing (not from the branch merge) and include files in cmd/backup/, cmd/create/, cmd/debug/, cmd/delete/, and others.

Impact

• npm run fmt:check fails if run on full codebase
• CI lint lane may flag these depending on scope
• Inconsistent code style

Proposed Solution

Run gofmt -s -w . to fix all formatting, then commit as a standalone formatting fix.

Acceptance Criteria

• gofmt -l . returns empty output
• npm run fmt:check passes
• All tests still pass
