Standardize on error wrapping in CLI

[dmjb]

Description:

Convert all fmt.Errorf(..., %v, err) to fmt.Errorf(..., %w, err) to enable proper error chain wrapping. This improves error debugging throughout the codebase. There are multiple parts of the codebase which have this issue.

Background:

• Codebase uses a mix of %w and %v.
• Using %w enables errors.Is() and errors.As() checks

Tasks:

• Replace all instances of %v with %w in the CLI when handling error types.

Pattern:

// BEFORE:
return fmt.Errorf("failed to create manager: %v", err)

// AFTER:
return fmt.Errorf("failed to create manager: %w", err)

Acceptance Criteria:

• All instances of %v converted to %w when handling error types
• All tests pass
