Switch from pkgs.stdenv (nixpkgs-25.11) to pkgsJs.stdenv (nixpkgs-22.11)
for Darwin daedalus derivation to fix native module compilation issues.

Root cause:
- Darwin native modules (bigint-buffer, blake-hash, etc.) fail to compile
  with the newer clang 21.1.7 from nixpkgs-25.11
- These modules were built/tested with the older toolchain from
  nixpkgs-22.11-darwin
- Using mismatched stdenv and darwin frameworks causes compilation errors

Solution:
- Use pkgsJs.stdenv.mkDerivation for the main daedalus package
- This provides the older, stable Darwin toolchain that native modules expect
- Aligns with existing use of pkgsJs.darwin frameworks and pkgsJs.python3
- Removes the clang++ wrapper that was causing 'Argument list too long' errors

The wrapper approach is no longer needed because:
- CXXFLAGS=-Wno-error is set via environment variables in patchElectronRebuild
- Using the correct stdenv avoids the enum-constexpr issues entirely

Native module compilation during electron-rebuild fails because newer
clang enforces strict enum checking. Environment variables don't
propagate through the electron-rebuild -> node-gyp -> make -> clang++
chain.

Solution: Create a clang++ wrapper that automatically adds -Wno-error
to all compiler invocations. This intercepts the compiler calls from
make during native module builds.

Changes:
- Updated node_modules derivation to use -Wno-error instead of
  -Wno-enum-constexpr-conversion for npm_config_cxxflags
- Updated daedalus derivation to match
- Updated rebuild-native-modules.sh script to export the flag with multiple
  variations for compatibility

The -Wno-enum-constexpr-conversion flag is not supported by older clang
versions in nixpkgs-22.11 (used for aarch64-darwin native builds). Using
-Wno-error makes all warnings non-fatal and works across all clang versions,
fixing blake-hash compilation errors.

This fix applies to:
- x86_64-darwin (cross-compiled on aarch64)
- aarch64-darwin (native builds)

Fixes the enum constexpr conversion error in node-addon-api header that
occurs when compiling native Node.js modules with newer clang that enforces
stricter enum type checking.
