feat: add configurable timeout for command execution

- Add commandExecutionTimeout setting to VSCode configuration (1-300 seconds, default 30s)
- Implement timeout logic in executeCommand function with proper cleanup
- Add timeout status to CommandExecutionStatus type
- Include comprehensive tests for timeout functionality
- Abort running processes when timeout is reached
- Provide clear timeout error messages to users

Addresses Slack mention request for configurable command execution timeout.
