Merge f7dc45d3a643063e653e0dcda9faeb9973ad93b5 into c052a16f72af7dd7671d4dd62826de71cd99dfb6

* thx seproDev, bashonly: yt-dlp/yt-dlp#12760, yt-dlp/yt-dlp#12761:
  - Improve nested attribute support
  - Pass global stack when extracting objects
  - interpret_statement: Match attribute before indexing
  - Fix assignment to array elements with nested brackets
  - Add new signature tests
  - Invalidate JS function cache
  - Avoid testdata dupes now that we cache by URL

* rework nsig function name search
* fully fixes #33102
* update cache required versions
* update program version
