Minor fixes: syntax issue and update cache manifest

[hemancini]

This pull request includes two changes related to the lapse.mjs file and the psfree_lapse.cache configuration file. The changes involve fixing a syntax issue in the exploit function and updating the list of cached files.

Code Fixes:

• lapse.mjs: Corrected a syntax error by ensuring the closing brace for the try block is properly placed. This resolves a potential issue with the kexploit function.

Configuration Updates:

• psfree_lapse.cache: Removed payload.js from the cached files list, likely to reflect updated project requirements or unused assets.
