pnpm 11.0.0-rc.5 on Node.js NPM

Patch Changes

Fix the @pnpm/exe SEA executable crashing at startup on Node.js v25.7+. Two separate regressions in @pnpm/exe@11.0.0-rc.4 are addressed:
1. pnpm pack-app now pins the Node.js used to write the SEA blob to the exact embedded runtime version. The SEA blob format changed in Node.js v25.7 (ESM entry-point support added a ModuleFormat header byte), so a blob produced by a pre-25.7 builder cannot be deserialized by a 25.7+ runtime and vice versa. In rc.4 the CI host Node.js (v25.6.1) built blobs embedded in a v25.9.0 runtime, tripping SeaDeserializer::Read() ... format_value <= kModule on every invocation. pack-app now downloads a host-arch builder Node.js of the target version when the running Node.js doesn't already match.
2. The pnpm CJS SEA entry shim now loads dist/pnpm.mjs through Module.createRequire(process.execPath) instead of await import(pathToFileURL(...).href). In Node.js v25.7+, the ambient require and import() inside a CJS SEA entry are replaced with embedder hooks that only resolve built-in module names, causing external file:// loads to fail with ERR_UNKNOWN_BUILTIN_MODULE. An explicit createRequire() bypasses those hooks.
