- Fix CWE-94 code injection in magic_commands.py by adding input validation
 and blocking dangerous shell commands in %% magic command handler
- Fix inadequate error handling in oi-mac-installer.sh by adding proper
 error handling for xcode-select --install command
- Fix CWE-400,664 resource leak in test_interpreter.py by ensuring proper
 cleanup of server processes in try-finally block
These fixes address critical security vulnerabilities that could allow
arbitrary code execution and resource leaks that could impact system
stability.

- Fix OS command injection in terminal.py by adding input validation
 to prevent malicious package names in sudo_install method
- Fix authorization bypass in display.py by adding proper screen
 parameter validation to prevent unauthorized screen access
These fixes prevent attackers from executing arbitrary commands through
package installation and accessing unauthorized screen captures.

- Fix authorization bypass in magic_commands.py by adding proper access
 control check for debug mode to prevent unauthorized access to sensitive
 message data
- Fix OS command injection in profiles.py by adding input validation and
 path verification to prevent malicious directory names in subprocess calls
These fixes prevent unauthorized access to debug information and block
command injection through directory parameters.

- Fix improper error handling in count_tokens.py by catching specific ImportError
 and adding proper warning messages instead of silently passing
- Reduce cyclomatic complexity in loop.py by extracting chunk processing logic
 into separate function for better maintainability
- Fix equality vs identity confusion in async_core.py by using isinstance()
 instead of type() == comparisons for proper type checking
- Fix exception swallowing in ai.py by moving return statement out of finally
 block to allow proper exception propagation
- Replace generic exceptions with specific ones in contacts.py and display.py
 using ValueError, RuntimeError, and ConnectionError for better error information
These fixes improve code maintainability, debugging capabilities, and follow
Python best practices for error handling and type checking.

- Fix path traversal vulnerability in wtf.py by adding filename validation
 and restricting file access to current directory to prevent unauthorized
 access to system files through directory traversal attacks
- Remove unprofessional language from commented code and replace with
 professional alternative to maintain code quality standards
These fixes prevent security vulnerabilities while ensuring the codebase
maintains professional standards appropriate for enterprise environments.
