First off, thanks so much for the addition of the flake.nix to the repo. It's been a monumental piece of work that I absolutely rely on.

However, I've noticed that the package built from the flake.nix takes up over 4GB of space.

Below is an AI generated report that may be helpful.

Summary

The OpenCode package is 4.0 GiB, which is excessive. Investigation shows that all platform-specific optional dependencies are being bundled instead of just the required platform.

Environment

• OpenCode version: v1.0.119
• Package manager: Bun
• Platform: Linux x64
• Installation: Via Nix flake from github:sst/opencode

Issue Details

The OpenCode Nix store package is 4.0 GiB:

$ nix path-info -Sh github:sst/opencode
/nix/store/q3p8pk2qk3ydsi2fdvnjl6raiydwdgyi-opencode-1.0.119  4.0 GiB

Nearly all of this size (4.2GB) comes from node_modules/.bun/ containing platform-specific binaries for all platforms instead of just Linux x64.
