fix: skill chips now correctly deselect and unhighlight when tapped again

[ckprojects77]

Summary

When a selected skill chip was tapped again to deselect
it, the tag disappeared from the selected skills list
but the chip itself remained highlighted in blue. This
happened because a duplicate nested fetch block in
script.js was causing a JavaScript syntax error that
crashed the entire script before event listeners could
register. With the broken code removed, the chip
selection state now stays in sync with the selected
tags clicking a chip highlights it and adds the tag,
clicking it again removes both the highlight and the tag.

rendering as visible text on the page due to a
prematurely closed input element.
