fix: Fix problems related to use terser nameCache

[zyrong]

1. The nameCache obtained in writebundle hook is not a reference to terseroptions
2. JSON.stringify(nameCache) requires converting regex to a string first.

This commit fixes the problems related to terser namecache. When terser compresses the code, the damaged variable names will be written to the namecache. Finally, the namecache will be written to the file system in this code, but after my test, it doesn't seem to work here
