fix: resolve multiple bugs in commitpulse

[saurabhhhcodes]

Description

This PR fixes real bugs found in the codebase:

• Replaced global isNaN with Number.isNaN: the global version coerces its argument, so isNaN('1') returns false while Number.isNaN is strict.
• Added rejection handler to Promise.all: an unhandled rejection in any input promise previously crashed silently.
• Added explicit radix to parseInt: without 10, strings like '0x1F' or '08' parse in unintended bases.
• Removed return undefined: bare return conveys the same intent without the redundant literal.

Type of Change

• Bug fix (non-breaking change fixing an issue)

How Has This Been Tested?

• Local manual testing

Checklist

• My code follows the style guidelines
• I have performed a self-review
