ci: use shamefully-hoist for bun compile compatibility

Bun's bundler can't follow pnpm's nested symlink layout to resolve
transitive dependencies of workspace packages (e.g. ink's yoga-layout,
react-reconciler). Adding shamefully-hoist=true creates a flat
node_modules layout that bun can resolve from, matching the behavior
of the local dev environment.
