v1.3.1

Fix:

• Let the allowlist override soft signals (e.g. variable expansions, subshells) to reduce prompt fatigue, while keeping a mandatory prompt override for deletion commands (such as rm or Remove-Item) to prevent accidental data loss

Chore:

• Perform codebase-wide cleanup: remove dead directories, update .gitignore, format Go code with gofmt, and remove stale TODO comments by @giveen in #82
