Missing ulid dependency in packages/opencode/package.json #1988

The ulid package is missing from the dependencies in packages/opencode/package.json, but it's required in packages/opencode/src/session/index.ts.

This issue only shows up when installing node dependencies with:

bun install --filter=opencode

which we use to package opencode in nix.

When installing node dependencies without the --filter flag running and building succeeds, because ulid is a dependency of other packages in the monorepo, so it gets installed transitively.
