Use 'failed to' prefix for top-level CLI error messages

[shiv-tyagi]

Gerund-style errors (e.g. "creating X: ...") are appropriate for internal helpers but ambiguous at the CLI boundary where the user sees them directly. Switch to "failed to " for all top-level errors returned from cmd/ action handlers.
