gemini-cli: fix file collisions

Multiple Node.js packages in nixpkgs create file collisions when installed together in home-manager or system profiles. Specifically:

- `gemini-cli` vs `eslint`: collision on `lib/node_modules/eslint/conf/default-cli-options.js`
- `gemini-cli` vs `angular-language-server`: collision on `lib/node_modules/semver/README.md` (with permission differences: 0555 vs 0444)

This occurs because these packages install their bundled dependencies directly to `$out/lib/node_modules/`, causing path conflicts when multiple packages provide the same transitive dependencies.

The issue stems from packages copying their entire `node_modules` directory to a shared location (`$out/lib/node_modules/`) rather than isolating their dependencies in package-specific directories.

Before:
```nix
cp -r node_modules "$out/lib/"
```

After:
```nix
cp -r node_modules "$out/share/gemini-cli/"
```

This is probably counterproductive in some ways (would ideally share deps?) but at least this fix allows these packages to coexist.
