fix(agentos): remove fetch override and export ShellSnapshot type

Remove the globalThis.fetch override (fetch-compat.ts) that buffered
ReadableStream request bodies for HTTP/1.1 compatibility. Export
ShellSnapshot and ShellReplayMode from the package index so downstream
consumers (agentos-apps) can name them in generated declarations.
