- Secure !shell_command execution by using shell=False and shlex.split.
- Fix inconsistent 'clear' command behavior; 'clear' now clears the screen.
- Align /model and /models commands; both now work for model operations.
- Improve error handling in core/parser.py for tree-sitter library loading:
  - Robustly determine path to ios_lang.so.
  - Add try-except blocks for OSError and other exceptions during load.
  - Ensure extract_functions handles parser load failures.
- Enhance error handling in core/repl.py for Ollama model queries:
  - Catch exceptions during model.query_ollama calls.
  - Provide user-friendly error messages if Ollama service is down or model is unavailable.

- Revamp welcome message with Rich Panel, Markdown, and random tips.
- Standardize error messages using a consistent Rich Panel style.
- Improve styling for file reading panels, model selection prompts, and multiline code input instructions.
- Implement a multi-stage dynamic progress indicator for LLM queries, providing more varied feedback.
- Enhance layout for /helpme, /tools, and /load_session commands with Panels and improved table styling for consistency and readability.

- Resolved issue with Rich text tags not rendering in the welcome message by using Text.from_markup for the panel content.
- Integrated pyfiglet to display a large ASCII art title ('CodeZ CLI') at startup.
- Added pyfiglet to requirements.txt.
- Adjusted welcome panel text and title to accommodate the new ASCII art.
