pnpm 10's post-build hoisting races when it hard-links one built package into several nested copies, and CI's clean install failed with ERR_PNPM_EEXIST on esbuild. vite resolved esbuild 0.28 alongside the 0.27 astro and tsup need, so it landed in five places; sharp 0.35 at the root left astro and miniflare with nested 0.34 copies. Override everything that accepts esbuild 0.27 to 0.27.4, hold wrangler on 4.101 (which pins 0.27.3 rather than 0.28.2), and keep sharp on 0.34 so astro and miniflare share the root copy.
