Create threadPool with max threads equal to CPU cores

Title: Create threadPool with max threads equal to CPU cores

Description:
There is a TODO comment in the packages/zenflux-cli/src/core/typescript.ts file that suggests creating a thread pool with a maximum number of threads equal to the number of CPU cores. This enhancement aims to optimize the threading model by avoiding the creation of an excessive number of threads, which can lead to performance degradation.

Location in Code:

// TODO: Avoid this, create threadPool with max threads = cpu cores.

Proposed Solution:
Implement a thread pool that dynamically adjusts the number of threads based on the available CPU cores. This can be achieved using Node.js's os module to determine the number of CPU cores and then configuring the thread pool accordingly.

Benefits:

• Improved performance by efficiently utilizing CPU resources.
• Reduced overhead from managing too many threads.
• Better scalability and resource management.

Priority: Medium

This issue will help track the progress of this enhancement and ensure it is addressed in a future update.
