Fix CI: add Phase 3 bun install to recreate per-package node_modules symlinks

The embedded workspace variant (installWorkspaceDeps) was missing the
re-install step after copying source files with withDirectory. This
overwrote per-package node_modules/ symlinks, preventing TypeScript
from resolving astro/tsconfigs/strictest in the frontend tsconfig,
which caused 376 ESLint type-resolution errors in CI.
