fix(lint): resolve golangci-lint errors for clean CI

Fixes 5 linting issues to allow PR checks to pass:
1. hooks.go: Explicitly ignore error in async goroutine
2. 022_drop_edge_columns.go: Handle deferred PRAGMA error
3. flags.go: Add nosec comment for validated file path
4. create_form.go: Fix American spelling (canceled vs cancelled)
5. create_form.go: Explicitly mark cmd parameter as required by cobra
These are pre-existing issues in the codebase, fixed here to
enable clean CI for the import deduplication fix.
