Node.js introduced a new SEA (Self-Extracting Archive) integration enabling bundled assets to be mounted as a read-only virtual file system (VFS) when the 'useVfs' option is enabled in the SEA configuration.

Previously, bundled assets could not be accessed transparently as a virtual file system, limiting how the main script and its dependencies could be executed and resolved within the SEA environment.

The PR implements a SEAProvider that mounts bundled assets lazily as a read-only VFS at runtime, with no fixed mount path. The main script runs inside this mount, enabling __filename, __dirname, require(), and ESM imports to resolve relative to the virtual file system. Asset content is loaded on-demand from the SEA blob, and the system supports both CommonJS and ESM entry points while disallowing conflicting options like 'useSnapshot' or 'useCodeCache'.

Mounting bundled assets as a virtual file system inside SEA improves modularity and runtime resolution of embedded resources, enabling seamless execution of main scripts and dependencies within a controlled, read-only environment without duplicating source files at build time.
