Description

The Nix CLI build (nix/opencode.nix) fails because build.ts embeds the web UI by default (bun run --cwd ${appDir} build), which invokes packages/app/node_modules/.bin/vite.

However, nix/node_modules.nix only installs dependencies for packages/opencode and packages/desktop:

bun install \
  --filter '!./' \
  --filter './packages/opencode' \
  --filter './packages/desktop' \

So packages/app/node_modules doesn't exist in the build sandbox — vite is missing entirely.

Root cause: nix/node_modules.nix is missing --filter './packages/app', and nix/opencode.nix is missing patchShebangs for packages/app/node_modules (like nix/desktop.nix already does for its own node_modules).

Suggested fix:

1. Add --filter './packages/app' to nix/node_modules.nix so app dependencies are available
2. Add patchShebangs packages/app/node_modules and nodejs to nativeBuildInputs in nix/opencode.nix (same pattern as nix/desktop.nix)
