fix: resolve 4 bugs in SnapPass-AI

[saurabhhhcodes]

Description

This PR fixes real bugs found in the codebase:

• Removed redundant boolean comparison: x === true is equivalent to x (and x === false to !x), and shorter to read.
• Replaced global isNaN with Number.isNaN: the global version coerces its argument, so isNaN('1') returns false while Number.isNaN is strict.
• Filled empty catch block: silently swallowing the error hides failures; now logs for debugging.
• Added rejection handler to Promise.all: an unhandled rejection in any input promise previously crashed silently.

Type of Change

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

How Has This Been Tested?

• Local manual testing
