refactor: simplify CLI layout by integrating inline completions

- Updated the HermesCLI layout to replace the floating completion menu with an inline CompletionsMenu, ensuring it appears consistently below the input area.
- This change enhances user experience by maintaining visibility of completions even after agent output fills the terminal, improving usability in non-full-screen modes.
