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.
• Simplified empty-string validation: comparing trim() to '' misses whitespace-only input; .trim().length === 0 is explicit.
• Added explicit radix to parseInt: without 10, strings like '0x1F' or '08' parse in unintended bases.
• Added explicit radix to parseInt: without 10, strings like '0x1F' or '08' parse in unintended bases.

Type of Change
