🦩 🔴 lib-finder.js dispatches on process.platform without a default/other-platform branch, silently returning undefined

Added a default: case to the switch(process.platform) statement in find() that returns an empty array [], matching the platform-stub convention of returning a safe empty value instead of falling through and returning undefined. This ensures callers iterating over the return value on unsupported platforms (win32, darwin, etc.) receive an empty array rather than throwing a TypeError.

(Automatically downgraded: no change in this fix lands near this finding's line — verify whether it was actually addressed.)

What the draft fix changed: Added a `default:` case to the `switch(process.platform)` statement in `find()` that returns an empty array `[]`, matching the platform-stub convention of returning a safe empty value instead of falling through and returning `undefined`. This ensures callers iterating over the return value on unsupported platforms (win32, darwin, etc.) receive an empty array rather than throwing a TypeError.
