Feat: Parallelism for process (#20)

* cpu: avoid hitting gpu hwmom sensors in polling

refactor: workers for data collection

refactor: improve CPU info retrieval and testing for core usage

* refactor: update CPU polling interval to improve accuracy in usage metrics

* refactor: enhance CPU temperature retrieval logic to improve accuracy and avoid GPU sensor interference

* fix: lint

* refactor: improve concurrency handling

* fix: lint
