Replace IFD with build-time read for -env job generation 
The previous IFD approach forced cross-platform builds during evaluation,
which could cause issues when Hydra evaluates on x86_64-linux but needs
to evaluate aarch64-darwin shells.

This new approach reads the mkShell output at build time using cat,
avoiding both:
- IFD which forces builds during evaluation
- recursive-nix which is not supported on remote builders

The shell is now a normal build dependency, and its output (containing
"declare -x VAR=value" lines) is read at build time to construct the
wrapper script.

Temporarily disable JS backend builds in CI 
The JS backend builds fail due to a hash mismatch in the
head.hackage.ghc.haskell.org fixed-output derivation in haskell.nix:
  specified: sha256-5gKLigkUTkkABGG8B9zNq8NKRIHv97K9No4kTLK/GyQ=
  got:       sha256-AO/vHIMSIBwjbp5GY561SmnPr5qTTyBt9ruy8D3lKZI=

This filters out all *-js-* shells from hydraJobs while keeping them
available in devShells for local development.

TODO: Remove this filter once upstream haskell.nix fixes the hash.
