CLI output is unclear when command fails or partially succeeds

### Description
When running `mesh-cli` commands, the CLI output can be unclear or ambiguous.
It’s hard to understand whether the command actually succeeded, failed, or exited early.

### To Reproduce
1. Install `mesh-cli`
2. Run a basic command with minimal or default config
3. Observe the CLI output

---

### Expected behavior
The CLI should clearly indicate:
- Whether the command succeeded or failed
- What went wrong (if anything)
- What the next action should be
