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.

The -env jobs previously used recursive-nix to run `nix print-dev-env`
inside a derivation, but this fails on remote builders with:
  "recursive-nix is not supported yet by external derivation builders"

This commit replaces that approach with Import From Derivation (IFD):
- Read the mkShell output directly at evaluation time via builtins.readFile
- Filter out the self-referencing $out variable to break circular deps
- Embed the environment content directly in the wrapper script

The mkShell output already contains "declare -x VAR=value" lines which
is exactly what's needed. This approach:
- Avoids the recursive-nix requirement entirely
- Still includes all runtime dependencies (GHC, cabal, tools, etc.)
- Works on remote builders without special configuration
