Add blank lines before return statements in all files to satisfy the nlreturn linter. This improves code readability by providing visual separation before return statements. Changes made across 24 files: - internal/cli/*.go - internal/secret/*.go - internal/vault/*.go - pkg/agehd/agehd.go - pkg/bip85/bip85.go All 143 nlreturn issues have been resolved.
