feat: add cleanup support for Elixir, Haskell, OCaml, and Editors

Windows port of biplavbarua's extended dev cleanup feature:
- Elixir: Mix archives and Hex cache cleanup
- Haskell: Cabal packages/store and Stack programs cache
- OCaml: Opam download and repo cache
- Editors: VS Code, VS Code Insiders, Zed, Sublime Text, Atom caches

Mirrors the macOS implementation from PR #287
