fix: resolve multiple bugs in commitpulse

[saurabhhhcodes]

Description

This PR fixes real bugs found in the codebase:

• Fixed default sort: .sort() coerces elements to strings, so [10, 9, 2] sorts as [10, 2, 9]; numeric comparator sorts correctly.
• 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.
• 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
